The trouble is mksignames actually has to run on the target
architecture to generate the appropriate signal names.  I don't know
if there's any way of doing that at all with autoconf.  Any more
ideas?  We could maybe make it conditional on not cross-compiling,
since it does solve the #include problem fairly neatly.

In principle this shouldn't be a problem, except that autoconf 2.13
doesn't seemed to have appeared on any mirror yet.  Even then I would
hope $(ZSH_EXEEXT) would just be empty for anyone who needed to run a
previous autoconf (which is supposed just people adding new patches to
the configuration behaviour), which wouldn't be so bad.  However, the
patch won't be in pws-8 because of the cross-compilation problem.
(Does anyone know this actually works at the moment?)
