We do now have Makefile.config being generated, (and we can move to
config.h to avoid the overly-long command-line problem if necessary).

Chris, do you want to tackle this one? ;-)

A really easy hack would be to detect glibc, and if present, use all the
existing code in notmuch. If not present, then use all the compatibility
functions. This could be by building a notmuch-compat.c that defines
functions like _notmuch_strndup() and then adding thins like:

	#define strndup _notmuch_strndup.

That would allow our current configure script to stay quite simple. If
people want more sophistication we could write functions in the
configuration script for doing test compiles to find functions, etc.
