From: Khem Raj <raj.khem@gmail.com>
Subject: [PATCH 08/12] libtool: Check for static libs for internal compiler libraries
Libtool checks only for libraries linked as -l* when trying to
find internal compiler libraries. Clang, however uses the absolute
path to link its internal libraries e.g. compiler_rt. This patch
handles clang's statically linked libraries when finding internal
compiler libraries.
