Disable sparc architecture for gcc 11 due to an recent gcc change
that broke uClibc-ng. The change was reverted by the patch
0005-Revert-re-PR-target-92095-internal-error-with-O1-mcp.patch
for gcc 8.4, 9.3 and 10.1 but stop maintaining it for newer gcc
releases.

Rutime tested:

 So, that means we will be forced to drop sparc support in a few years when we
stop maintaining GCC 10, right?

 I'm not crying over it, that's for sure :-)

Indeed but uclibc-ng is the only remaining libc we have for sparc32 (sparcV8).
The patch I reverted for gcc 8,9,10 broke the uClibc-ng port for sparc that was
not modified since more than a decade.

The problem is not easy to investigate since the system crash right after the
end of a forked process. For example, when you start 'ls' command, you'll see
the directory content just before the crash. For some reason uClibc-ng fail to
resume the initial process.

Well, even if it will not be a lost, the sparc defconfig was up-to-date and
running until now.

Best regards,
Romain
