[C] Fully expand directories before doing comparisons in configure.ac

[Michael Sperber]

I've committed this patch:

2006-11-23  Mike Sperber  <mike at xemacs.org>

	* configure.ac (XE_EXPAND_VARIABLE): Fully expand the various
	directories before comparing them for figuring out which of them
	are user-defined.  Use XE_EPXAND_VARIABLE macro created for this
	purpose where applicable.
