Some flag cleanup for the sanitizer runtimes.
This hoists most of the CFLAGS into a common variable. It also adds
detection for -Wno-c99-extensions and uses it to silence a pile of
warnings.
Finally, it switches to the proper flag -rdynamic.
With this, the cmake build is warning free on my bootstrap Linux build.
