I think this is because grub wants to be built 32 bit (presumably something to do with booting) and gcc is only built with a 64 bit libgcc due to the --disable-multilib configure option. I tried to remove the --disable-multilib option but then the gcc build dies with "cannot find -lc" while building libgcc.

I'd expect you need to recompile the c library as well for 32-bit.
(doesn't it say something like: "Skipping incompatible <...> while
searching for -lc" ?)

Best regards,
