[waffle] [PATCH] cmake: Fix test for thread-local storage

[Chad Versace]

Commit 6fcbe52 "cmake: Refactor compiler flags into new module" exposed a bug
in the test for thread-local storage, causing the test to always fail. If the
regex "warning|error" appears in the compiler log, then the test fails. This
causes false failures when the test invokes the compiler with
'-Werror=missing-prototypes'.

Fix the regex to more closely match gcc and clang error messages.
