extras/tools/libtool-2.4.6-clang-libs.patch

   1 Libtool checks only for libraries linked as -l* when trying to
   2 find internal compiler libraries. Clang, however uses the absolute
   3 path to link its internal libraries e.g. compiler_rt. This patch
   4 handles clang's statically linked libraries when finding internal
   5 compiler libraries.
