The recent git update of sawfish 1.5 broke

[Allan Duncan <amd2345 fastmail com au>]

I have been able to create an x64 rpm with a git as at April 28 after
tweaking the sawfish.spec, but the current 1.5.0 breaks due to a change
relating to po/Makefile in configure.in  There are file missing messages
about po/Makefile.in.in, and this spurious .in appears in several spots.
It appears that po/Makefile.in is now _supposed_ to be created on the fly.

Removing the .in from configure.in's po/Makefile.in just changes the error.

BTW, on both x86 and x64 boxes there is a problem with the machine type.
diffs to the sawfish.spec for a successful rpmbuild:
64c64
< %define _host %{_host_cpu}-redhat-linux-gnu
---
> %define _host %{_host_cpu}-pc-linux-gnu  (-unknown-linux-gnu on the x64)
