Sometimes we need to re-run configure, due to changes in configure

If configure was run with a long command line, it's tricky to get this
right again. However, this can be done automatically by the Makefile.
Presumably the right way to do this would be:
"make clean reconfigure ..."
otherwise you could get some kind of weird hybrid build. I'm not sure
that every change in spec.gmk, for example would force a recompile of
everything that depended on something in there. But perhaps it does?
By adding a new target 'reconfigure', if we have an existing
configuration, configure will be ran again with the same arguments as
last time.
Sometimes I've re-run configure with the exact same args and I get a
warning about doing this over an existing configuration ?? At which
point I either do a dist-clean or "rm -rf ...".
