[libvirt] [PATCHv2] build: allow 'make syntax-check' on fresh checkout

[Eric Blake]

For good or for bad, I did a fresh checkout, ./autogen.sh, then
'configure', then 'make syntax-check', and was surprised that it
failed.  Running 'make' before 'make syntax-check' cleaned up the
issue, but this patch makes it work up front.

* cfg.mk (sc_po_check): Add prerequisite.

I'm glad I didn't push it yet - it didn't work for VPATH.
