I've managed to get sbuild crosscompile to work for hppa and found the problem (it's a missing "XREF_SETUP()" line, not that the error message would give any hint to that...)
With that, I have 4 things to fix in the package: - postrm is missing cleanup for /var/lib/frr (piuparts failure) - stick in that missing line for hppa - drop the (BD-Uninstallable) libunwind dep on alpha,m68k,sparc64,x32 - the watch expression is a bit shit I'll put a -2 together later today. (ia64 is also failing build, but that very much looks like a general ia64 problem, not some FRR breakage.)
