There is only one place basename is used: mkdeps.c.  In general,
it appears that an effort was made to avoid it.  Here is a comment from
ChangeLog.1:

Mon May 17 23:56:39 1999  Alexandre Oliva  <oliva@dcc.unicamp.br>

        * Makefile.in (stmp-fixproto): Pass location of mkinstalldirs to
	fixproto.
	* fixproto: Avoid unportable constructs such as `basename' and
	`mkdir -p'.  Use mkinstalldirs from the environment if `mkdir -p'
	fails.

The libiberty version only builds if the system doesn't have it.  However,
the system version isn't portable according to the above comment.  This
probably is an argument for libiberty to always build basename.  Then, gcc
could likely use it.
