The new detection method was omitting -gnu from the triples which caused
some behavior changes in clang.

From 160d464a192f25a7e69bf63f20bdfdffe036dd42 Mon Sep 17 00:00:00 2001

Subject: [PATCH] test/ExecutionEngine: Clean up lit.local.cfg
Switch to using config.root.native_target to determine if tests are
supported. This is a canonical form of the arch from the target
triple.
