Android 7.1.1 kernel compile errors (tool chain)

The build environment is ubuntu 16.04 with latest gcc 5.4.0 and GNU Make 3.82. My target is an am335x custom board which can run android 4.4. I am going to support it for android 7.1.1.
The project is fetched from google android manifest tag android-7.1.1_r46 and the kernel is from msm tag android-7.1.1_r0.63. The cross compiler I am using is from prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin.
That is the environment information. I haven't installed the NDK or SDK yet because I saw the api level for android 7.1.1 is 25 while the newest NDK only support up to 24, so I get a bit confused what to do.
If I run the command: m -j8 uboot linux
The uboot compiles fine, but there are a lot of errors when compiling the linux kernel.

There are more errors behind.
I have googled around and most of the people say this is a tool chain problem. But I don't find a lot of instruction about how to install the tool chain properly especially for 7.1.1. There seems to be no tool chain needed for the android 4.4 kernel. I fetch the custom android 4.4 kernel and it compiles fine.

The problem above is because I downloaded a wrong version of Android kernel. What I downloaded is https://android.googlesource.com/kernel/msm/+/android-7.1.1_r0.63, and this is kernel v3.10.
Obviously this is not for Android 7.1.1 (which should be using kernel v4.4). So when I am trying to compile "old" kernel with the "new" cross compiler from the prebuilt, it generated whole bunch errors that the "old" compiler won't. I end up using the kernel from https://android.googlesource.com/kernel/common/+/upstream-linux-4.4.y upstream-linux-4.4.y branch, it is compatible with Android 7.0 to 7.1.2.
I have no idea why google name it as android-7.1.1_r0.63, but that definitely not for Android 7.1.1 to use. Hope nobody has the same problem as I did.

Syntax error: Unterminated quoted string [Makefile]

Not able to find the problem:
make PLATFORM=android
make[2]: Entering directory `/home/debian/Downloads/nonemaioq3'
CC code/client/cl_cgame.c
/prog/toolchain/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-gcc: 4: /prog/toolchain/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-gcc: Syntax error: Unterminated quoted string

and this is the Makefile I got:
http://pastebin.com/QYZYVvTn
I don't find any problem there :S Help please.

The line
CC code/client/cl_cgame.c
starts the compiler (C Compiler or CC). The error message is after the CC and doesn't start with make, so it relates to the compiler, not the Makefile.
/prog/toolchain/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-gcc: 4: /prog/toolchain/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-gcc: Syntax error: Unterminated quoted string
gcc is the GNU C compiler. The error is in the file /prog/toolchain/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-gcc, on line 4.
In view of your comment, "arm-linux" means that version of GCC is meant to run on ARM processors. If you are running this on a PC, you want a gcc with "x86" or "x64" in place of "arm." That would be a cross-compiling situation; see here for links on how to set that up.

How to prevent cmake adding "compatibility_version" for gcc?

I'm pretty new to cmake and i'm trying to cross-compile libftdi for ARM Linux (Android).
Why cmake adds "-compatibility_version" to gcc command-line which leads to error:
/softdev/arm-toolchain/bin/arm-linux-androideabi-gcc -O2 -g -DNDEBUG -dynamiclib -Wl,-headerpad_max_install_names -L/softdev/arm-libs/lib -compatibility_version 2.0.0 -current_version 2.0.0 -o libftdi1.2.0.0.dylib -install_name /Users/asmirnov/Documents/dev/src/libftdi-1.0/src/libftdi1.2.dylib CMakeFiles/ftdi1.dir/ftdi.c.o CMakeFiles/ftdi1.dir/ftdi_stream.c.o /usr/local/lib/libusb-1.0.dylib

make[2]: *** [src/libftdi1.2.0.0.dylib] Error 1
make[1]: *** [src/CMakeFiles/ftdi1.dir/all] Error 2
make: *** [all] Error 2
Since i can't find "compatibility_version" command-line parameter in supported by gcc parameters list is it cmake error or cmake configuration problem?
UPDATE: problem #1 solved (hacked)
i've solved the problem by commenting the next lines in ../Modules/Platforms/Darwin.cmake:
# 4ntoine (fix for libftdi compilation using cmake)
#set(CMAKE_C_OSX_COMPATIBILITY_VERSION_FLAG "-compatibility_version ")
#set(CMAKE_C_OSX_CURRENT_VERSION_FLAG "-current_version ")
#set(CMAKE_CXX_OSX_COMPATIBILITY_VERSION_FLAG "${CMAKE_C_OSX_COMPATIBILITY_VERSION_FLAG}")
#set(CMAKE_CXX_OSX_CURRENT_VERSION_FLAG "${CMAKE_C_OSX_CURRENT_VERSION_FLAG}")
# ...
# 4ntoine (fix for libftdi build using cmake)
#if(NOT XCODE)
# Enable shared library versioning. This flag is not actually referenced
# but the fact that the setting exists will cause the generators to support
# soname computation.
# set(CMAKE_SHARED_LIBRARY_SONAME_C_FLAG "-install_name")
#endif()
I know it's not good especially when you are not sure what you're doing ;)
Now i have another problem #2:

configure sphinxbase or pocketsphinx for android in ubuntu

I need to implement speech to text offline functionality for my android apps, I found library sphinxbase i tried to installed in ubuntu but something went wrong and the error occured.
I have download the both package of sphinxbase and pockectsphinx and placed in same directory , As document says i ran ./autogen.sh file successfuly after this one message occur to run make command to compile packages after make command there is some error occur

Strip off the space in the directory name.
Try renaming "speech to text" to "speechtotext".

I try to build the rt73.ko linux driver for android using cross complile. I have download the android NDK and the Kernel sources of the the target system (Rockchip RK3066) and when I build the driver I am getting the following error:

Could you please help me to overcome the above error?

Although you cross compile, only the kernel can be compiled. scripts/basic/fixdep is userland program.
To overcome this, you need to use http://crosstool-ng.org/ for example.
