I ran into it more than 2 years ago. I started working on ld first:

Wed Sep 16 07:32:44 1998  H.J. Lu  (hjl@gnu.org)

	* ld.h (args_type): Add one field, multilib_dir.

	* ldfile.c (ldfile_add_library_path): Add one argument, append.
	* ldfile.h (ldfile_add_library_path): Likewise.

	* ldgram.y: Calling ldfile_add_library_path with one more
	argument, true.
	* ldmain.c: Likewise.
	* lexsup.c: Likewise.

	* ldmain.c (check_for_scripts_dir): Add one argument, append.
	(main): Initialize command_line.multilib_dir to NULL.
	(set_scripts_dir): If command_line.multilib_dir is not NULL,
	prepend it to search path.

	* lexsup.c (OPTION_MULTILIB_DIR): New.
	(parse_args): Handle OPTION_MULTILIB_DIR.

	* emultempl/elf32.em (gld${EMULATION_NAME}_get_script): If
	command_line.multilib_dir != NULL, get linker scripts from
	files.

The idea is you can tell ld with "ld --multilib-dir path". ld will
search path for the needed files. But I didn't have time to change
the gcc driver for crt*.o.
