Hmm - seems doable. There are obviously some (most)
ports not defining __HAVE_SIGINFO in libc and using
obsolete names for SYS_*sigreturn*, but this should cause
build errors and is easily identified.
(The libc sigreturn() implementations have bugs
anyway, see eg on alpha:
$ nm /lib/libc.so|grep sigreturn
0000000000029710 T compat_16___sigreturn14
00000000000696e0 T sigreturn
)

I've put some glue code there which makes hppa use ksiginfo
just as container for signo and code, so it looks like
SIGINFO using for the rest of the kernel. Not nice, but
still better than completely breaking it...
