| 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. |
