package/pkg-cmake: remove override of CMAKE_ASM_COMPILER
CMAKE_ASM_COMPILER is supposed to point to a compiler wrapper (i.e.
gcc), _not_ to as directly. If it is not set, it will use the value of
CMAKE_C_COMPILER. That's exactly what we want, so there is no need to
set CMAKE_ASM_COMPILER at all.
For target, we don't set CMAKE_ASM_COMPILER either.
Setting CMAKE_ASM_COMPILER leads to build failures for any package that
actually tries to build .S files for the host - like llvm. This is why
llvm has an override for it.
