There's something weird going on here.
If I just download & install gcc-11-hppa64-linux-gnu from Debian, this
config file builds just fine.
If I invoke make.cross as you have it here, I see the same error you
report.
Adding 'V=1' to this, shows:
sh ../scripts/atomic/check-atomics.sh
/home/willy/0day/gcc-9.3.0-nolibc/hppa-linux/bin/hppa-linux-gcc [...]
which is weird, right? It's not hppa64, and it's not gcc-11.2. So my
suspicion here is that there's some bug in your tooling which is reporting
a bogus error. You're probably better situated to debug this further
than I am.
Oh, and I checked, in case the filename was confusing me:

So it really is a 32-bit hppa build, and it really is gcc 9.3, not 11.2.

Sorry for the confusion here, we recently updated the way to build parisc
64 bit in the right way. But the change to make.cross (for reproducer) is
still under review.
We will double check this report and update make.cross to provide update
to you.

There's something weird going on here.
Hi Matthew,
Sorry for the inconvenience, it's a false positive, the problem is
ARCH=parisc was used to build the 64 bit kernel.
the actual command should be:
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-11.2.0 make.cross
O=build_dir ARCH=parisc64 prepare
Best Regards,
Rong Chen
