This patch implements the Solaris 11.[0-3] obsoletion just announced in
https://gcc.gnu.org/pipermail/gcc/2022-December/240322.html
Bootstrapped without regressions on Solaris 11.3 (i386-pc-solaris2.11,
sparc-sun-solaris2.11 without and with --enable-obsolete) and 11.4.
Ok for trunk?
While I've been extra careful with the config.gcc part to make it work
correctly in native and cross configurations, it would be good if some
build maintainer could check.
The trouble is that config.guess doesn't include the minor version in
the triple and even if that were to change now, it's guaranteed to break
lots of code that doesn't expect this, so I'm doing the determination
locally.
Thanks.
