I don't think the differences between cross and native builds are
documented anywhere.

I would say it dies in the dynamic linker before zic is entered.

No.  The 2.2.4-1 patch adds the debian-specific patches to the tarball.
There's nowhere to get the hppa patch from if you don't apply the
2.2.4-1 patch.

glibc 2.2.4 is indeed not yet available for hppa.  As it says in the
release announcement.

Because we can't implement testandset atomically & efficiently on hppa.
The places which use testandset actually just need trylock.
