Please see https://bugs.gentoo.org/908258. There were miscompilations
even fixed after 12.3.0 was tagged.

(Also, ccache really isn't a "package with quirky behaviour" in terms of
whether or not it causes gcc to ICE. It has nothing to do with what
ccache itself does at runtime.)

It should get a bit better as of recent 13 as we backported a change
to help parallel builds at least (and reduce resource consumption).

(Also, added toolchain@ to CC...)
