The non-cross gcc already is at 13.  Fedora builds the distro with
pre-release gcc so gcc gets some serious real-world testing before
release.

The cross compilers lagging behind a bit, not sure whenever there is
some actual problem or whenever maintainers are just waiting for the
final gcc-13 release.

While that works as temporary stopgap for edk2 CI it is a non-starter
for fedora distro builds.  Any builds must be done using compilers
shipped by fedora.  So, fedora shipping edk2-loongarch (or
ipxe-loongarch) packages is blocked by this.

I'll go just wait for gcc-13 cross compilers land in fedora then.

take care,
