When compiling LLVM headers, including llvm-config.h, we need to respect LLVM_CFLAGS. This is especially crucial if LLVM is located in a non-standard location and it happens that llvm-config.h includes another header. In such case the detection would fail due to missing header, because the path is provided in LLVM_CFLAGS. Let's add LLVM_CFLAGS to global CFLAGS for the time of detection and then restore the original flags, as done in other places of the script.
