[Mesa-stable] [PATCH] configure: Strip LLVMX86Asm* dependencies.

[Gustaw Smolarczyk]

They are picked automatically by the provided llvm-config flags, but are
not needed.

Fixes loading radv through a vulkan loader.

It's work-around for:
https://lists.freedesktop.org/archives/mesa-dev/2016-October/130765.html

Since there are other people than me dealing with this issue, might
as well propose a patch that work-arounds it for me for these other
people to benefit from.

It's my first patch to the stable release, I hope I did it right.
