ld/configure.host patch for ia64-linux

[Jim Wilson <wilson at cygnus dot com>]

This is another patch I missed when adding the ia64-linux support a few weeks
ago.  I checked in the following patch which adds ld testsuite support for
ia64-linux.  After I added this patch, I noticed that it was missing the
change to use ${CC} instead of gcc, so I checked in a second patch to fix
that.

	* configure.host: Added HOSTING_CRT0, HOSTING_LIBS for
	host "ia64-*-linux-gnu*".
