[PATCH, modula2] PR-108182 gm2 driver mishandles target and multilib options

here are some patches which attempt to allow target specific include
paths and library paths in the gm2 driver.  I admit that the patch has
flaws in that it only processes options -f, -m in the lang_specific_driver.
[Called after driver::set_up_specs but before read_specs is called].

I suspect a better implementation might include a language callback
(lang_post_spec) which could fixup target related paths.

gcc/ChangeLog:

        * gcc.cc (save_switch): Remove static declaration.
        (get_multilib_dir): New function.
        (reset_mdswitches): New function.
        * gcc/gcc.h (save_switch): Declare extern.
        (get_multilib_dir): New extern.
        (reset_mdswitches): New extern.

gcc/m2/ChangeLog:

        * gm2spec.cc (lang_specific_driver): Detect -m and -f options and
        call save_switch.  Assign multilib_dir with the result of
        get_multilib_dir.  Call reset_mdswitches afterwards.
