[Mesa-dev] [PATCH 05/17] configure.ac: Mandate --enable-gallium-llvm when checking LLVM version

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

With this change we effectively require --enable-gallium-llvm when
building RADV. This should be perfectly safe since the gallium radeonsi
driver already explicitly requires it.

The "gallium" part in --enable-gallium-llvm is about to be removed soon
(not in stable) but until then make sure that things can build.

To reflect the requirement (as opposed to check previously) rename
llvm_check_version_for to llvm_require_version
