  We need the multilib paths in gcc to find e.g. glibc crt files on
Debian.  This is essentially based on t-linux64 version.

gcc/ChangeLog:

	* gcc/config/i386/t-gnu64: New file.
	* gcc/config.gcc [x86_64-*-gnu*): Add i386/t-gnu64 to
	tmake_file.

(and it'd be useful to have it backported to the 13 branch)
