more junk goes away...

[Zack Weinberg <zack at codesourcery dot com>]

now we have build libiberty, gen* don't need their own copies of
xmalloc.

bootstrapped i386-linux.

zw

	* gencheck.c, gengenrtl.c: don't define xmalloc.
	* gensupport.c: don't define xstrdup, xcalloc, xrealloc,
	xmalloc.
	* f/fini.c: use xmalloc.
