--- Comment #10 from Christophe Lyon <clyon at gcc dot gnu.org> ---
Can you try to revert my patches:
f0d3b6e384a68f8b58bc750f240a15cad92600cd
ccb9c7b129206209cfc315ab1a0432b5f517bdd9
and remove your patch at comment #5 ?
You should still see the problem you reported in bug #108011


However, I don't understand why you had to do what you describe in comment #8.
When multilibs are disabled, the build shouldn't try to use MULTILIB_OPTIONS
etc...
