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: $ /home/willy/0day/gcc-9.3.0-nolibc/hppa-linux/bin/hppa-linux-gcc -v Using built-in specs. COLLECT_GCC=/home/willy/0day/gcc-9.3.0-nolibc/hppa-linux/bin/hppa-linux-gcc COLLECT_LTO_WRAPPER=/home/willy/0day/gcc-9.3.0-nolibc/hppa-linux/bin/../libexec/gcc/hppa-linux/9.3.0/lto-wrapper Target: hppa-linux Configured with: /tmp/build-crosstools-xh/gcc/gcc-9.3.0/configure --target=hppa-linux --enable-targets=all --prefix=/tmp/build-crosstools-xh/cross --enable-languages=c --without-headers --disable-bootstrap --disable-nls --disable-threads --disable-shared --disable-libmudflap --disable-libssp --disable-libgomp --disable-decimal-float --disable-libquadmath --disable-libatomic --disable-libcc1 --disable-libmpx --enable-checking=release Thread model: single gcc version 9.3.0 (GCC)
So it really is a 32-bit hppa build, and it really is gcc 9.3, not 11.2.
