Support TIC6X

TI C compiler > 8.0.0 has supported C99. So I try to transport x264 to this compiler.

Prepare:

Download and install TI compiler from https://www.ti.com/tool/CCSTUDIO (TI IDE contains the latest comiler) or by your package manager (for my linux distribution, it is https://aur.archlinux.org/packages/ccstudio).

Run:

export C6X_C_DIR=/opt/ccstudio/ccs/tools/compiler/ti-cgt-c6000_8.3.12/include;
/opt/ccstudio/ccs/tools/compiler/ti-cgt-c6000_8.3.12/lib export PATH=PATH:/opt/ccstudio/ccs/tools/compiler/ti-cgt-c6000_8.3.12/bin ./configure --disable-cli --enable-static --disable-bashcompletion
--disable-opencl --disable-thread --disable-interlaced --bit-depth=8
--chroma-format=420 --disable-asm --enable-debug --disable-avs
--disable-swscale --disable-lavf --disable-ffms --disable-gpac
--disable-lsmash --host=tic6x-ti-none make -j$(nproc) example
