build: Use -ffreestanding
this is a stand-alone/baremetal application, therefore demanding
-ffreestanding would help it compile with hosted toolchains e.g. ( linux
toolchains ), it also ensures that it won't be using platform
optimizations like inlining mem* str* functions which gcc might decide
especially with wrapper string functions in opensbi code
