[PATCH 2/9] configure: Add --with-llvm-shared-libs
From: Tom Stellard <tstellar@gmail.com>
This option allows targets to link against the LLVM shared library
instead of the static libs. With LLVM 2.9, his saves ~11 MB for each of
the r300 target libraries.
(cherry picked from commit 7d87c71a70c95d4fe3a94676128fd9524f048112)
