gitmodules: Fix tracking branch for GCC 12

A recent commit bumped the GCC version to 12.2,
but adjusting the tracking branch in .gitmodules was forgotten.
Let's fix this and set the tracking branch to gcc-12
(note, that there are no release branches for minor version releases).

I'm trying to clean up some of my test scripts, and one issue is that
I've got two QEMU builds: one for user-mode emulation and one for
system-mode emulation.  This adds an autoconf flag that allows me to
avoid the duplication.

currently does not support rv32 and thus can't be enabled by default.
