LLVMInitializeAMDGPU* functions need to be explicitly declared
and mesa expects them via <llvm-c/Target.h> header,
but LLVM needs to be instructed to invoke its own LLVM_TARGET(AMDGPU) macro,
or the functions will not be available.
A new llvm cflag (-DFORCE_BUILD_AMDGPU) serves this purpose,
the same mechanism is used also by other llvm targets e.g. FORCE_BUILD_ARM
A necessary prerequisite is to have AMDGPU target handled accordingly
in llvm config files i.e. {Target,AsmParser,AsmPrinter}.def
for llvm device build includes.
This avoids the following building errors:
