s390: boot, purgatory: pass $(CLANG_FLAGS) where needed
The purgatory and boot Makefiles do not inherit the original cflags,
so clang falls back to the default target architecture when building it,
typically this would be x86 when cross-compiling.
Add $(CLANG_FLAGS) everywhere so we pass the correct --target=s390x-linux
option when cross-compiling.
