Hi Jiri,
Thanks for testing on parisc!

since the "parisc: Add vDSO support" commit, I can no longer
cross-build a hppa kernel. I see two issues:
1) CROSS32_COMPILE detection doesn't work here, as openSUSE provides
hppa-suse-linux-* binaries. It's easy to overcome by
"CROSS32_COMPILE=hppa-suse-linux-"
How is it handled for other platforms like s390x?
s390 simply uses CC for vdso32:
cmd_vdso32cc = $(CC) $(c_flags) -c -o $@ $<
Would it make sense to add the detection for SUSE too?
Maybe.
So, could 1) be fixed on the Kconfig side? Or should I (people running
SUSE) use "CROSS32_COMPILE=hppa-suse-linux-"?
2) openSUSE doesn't provide any libc for hppa. So gcc doesn't provide
libgcc.a and the build of vDSO fails.
libgcc.a comes with the compiler, I don't think you need libc for that.
I was told glibc is needed to build libgcc.a.
2) was fixed on the compiler (SUSE) side. cross-hppa-gcc12-bootstrap was
introduced -- note it's known to be a misnomer -- it should have been
like s/-bootstrap/-baremetal/.
