There has been a frequent complaint of:
make[2]: Entering directory `/home/remote/eblake/libvirt/po'
make[2]: *** No rule to make target `/config.status', needed by `Makefile'.
Stop.
It happens after nuking and regenerating the po directory,
which is a common action after running anything like
'make dist' or 'make rpm' that dirties all the .po files.
Teach autogen.sh that it must regenerate po/Makevars to avoid
the missing variable declaration, and teach cfg.mk to recognize
that a nuked po directory is cause to rerun autogen.sh.
* cfg.mk (_update_required): Check for po/Makevars.
* autogen.sh (bootstrap): Run bootstrap if it got lost.
Diagnosed by Justin Clift.

Tested by 'git clean -x -f po && make'. A bit drastic
(I prefer 'git checkout po' as the fastest way to undo
local changes to the po directory caused by 'make dist',
since that won't erase po/Makevars), but using that
sledgehammer to clean po/ proves that this patch works.
This should even work in a VPATH build :)
