Thanks for the fix.

I think 'po/Makefile.in.in' is not a checked-in file
(it's autogenerated during the bootstrapping process),
so this patch is good for the tarballs, but not for the git
repositories.

I do see that projects the use gnulib with non-recursive makefiles
include gnulib's 'non-recursive-gnulib-prefix-hack' module
and contain this in 'bootstrap.conf':

   bootstrap_post_import_hook ()
   {
       ...
       # Massage lib/gnulib.mk before using it later in the bootstrapping 
process.
       build-aux/prefix-gnulib-mk --lib-name=$gnulib_name lib/$gnulib_mk
   }

So perhaps that would be a good place to
patch Makefile.in.in as you suggested ?
