[Libguestfs] [PATCH] build: avoid locale-specific changes in generated, VC'd file

[Jim Meyering]

When I build with LC_ALL=C in my environment,
the all-local rule generates po/POTFILES.in that
is sorted differently from the on that is checked in:

    diff --git a/po/POTFILES.in b/po/POTFILES.in
    index ca01b3d..154915a 100644

     src/guestfs-actions.c

If we generate that file so that sort always uses the C locale, then,
this type of difference will not arise.  Here's the patch to fix the
rule as well as to reflect the change in the generated file:
