hisi cross platform compile error ,
modify build.sh pi config to CROSS_PREFIX=aarch64-himix100-linux-
use ./build.sh all pi release
and i got this error :
==== build pi libhal done.
==== build pi libsubmask done.
==== build pi libskt done.
gcc: error: missing argument to ‘-L’
make: *** [test_librpc] Error 1

another problem is i use run objdump -d libbase64.so
it show libbase64.so： elf64-x86-64, not elf64-little

Fixed it, lua and x264 also need porting by yourself
