This update for gcc12 fixes the following issues:

This update ship the GCC 12 compiler suite and its base libraries.

The compiler baselibraries are provided for all SUSE Linux Enterprise 15
versions and replace the same named GCC 11 ones.

The new compilers for C, C++, and Fortran are provided for SUSE Linux
Enterprise 15 SP3 and SP4, and provided in the "Development Tools" module.

The Go, D and Ada language compiler parts are available unsupported via the
PackageHub repositories.

To use gcc12 compilers use:

- install "gcc12" or "gcc12-c++" or one of the other "gcc12-COMPILER" frontend packages.
- override your Makefile to use CC=gcc12, CXX=g++12 and similar overrides for the other languages.
