+Subject: [PATCH] [Driver] Give devtoolset path precedence over InstalledDir
+
+This is a followup to the change from c5fe10f365247c3dd9416b7ec8bad73a60b5946e.
+While that commit correctly adds the bindir from devtoolset to the
+path, the driver dir / install dir still comes first. This means
+we'll still end up picking /usr/bin/ld rather than the one from
+devtoolset.
+
+Unfortunately, I don't see any way to test this. In the environment
+the tests are run, this would only result in a behavior difference
+if there is an ld binary present in the LLVM build directory, which
+isn't the case.
