configure.ac: Only add default LLVM components if needed
configure.ac: Only add default LLVM components if needed

LLVM components are only added when LLVM is needed.
This means gallium adds this as soon as "--enable-gallium-llvm"
is "yes" and radv + opencl add it explicitly.

v5:
Removed hunk that disabled LLVM for gallium if it was not found.
