+Subject: [PATCH] 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.
