--target-os=OS compiler targets OS [$target_os]
--target-exec=CMD command to run executables on target
--target-path=DIR path to view of build directory on target
+ --toolchain=NAME set tool defaults according to NAME
--nm=NM use nm tool
--ar=AR use archive tool AR [$ar_default]
--as=AS use assembler AS [$as_default]
--disable-mmi disable MMI optimizations
--disable-neon disable NEON optimizations
--disable-vis disable VIS optimizations
+ --disable-inline-asm disable use of inline assembler
