[Mesa-stable] [PATCH 7/7] configure.ac: static link LLVM by default

[Emil Velikov]

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

A while back Michel reported that LLVM has symbol versioning to avoid
symbol collisions. Based on observations LLVM 5.0 is the first upstream
version to actually has it.

The Debian/Ubuntu packaging has local patches for that, going back to
LLVM 3.7.

Since symbol collisions do come up again and again (fortunately not so
often) let's flip the switch back to static.

The toggle is still there for those interested in linking to the shared
version of the library.
