-Subject: [PATCH] Driver: Add a gcc equivalent triple to the list of triples to
- search
-
-There are some gcc triples, like x86_64-redhat-linux, that provide the
-same behavior as a clang triple with a similar name (e.g.
-x86_64-redhat-linux-gnu).  When searching for a gcc install, also search
-for a gcc equivalent triple if one exists.
