[PATCH] maintainer-makefile: make sc_po_check easier to tune

[Eric Blake]

* top/maint.mk (sc_po_check): Allow overriding which non-VC files
to probe for strings, such as an alternate location for gnulib.

Signed-off-by: Eric Blake <address@hidden>

Needed for (and tested with) libvirt, where gnulib files live in
$(srcdir)/gnulib/lib/*.[ch] rather than the default, and where we
also want to ensure xgettext scans some generated files not in git.
