Alan Coopersmith 8b6a750097 Fix gcc warnings about redundant declarations of fallback functions ...

Ensure ffs, strndup, strlcat, etc. aren't defined by our headers
if they're already defined in the system headers.

This does export the HAVE_FFS, HAVE_STRNDUP, etc. definitions to drivers,
but if you built the Xserver with a libc that had those, and then build
the drivers with a less capable libc, you're going to have problems anyway,
and this should solve some reported problems with conflicts between our
strndup definition and gcc magic for it.
