My plan is to (a) wait for a release of wcslib with the necessary 
patches, and then (b) move our local copy into cextern, and (c) provide 
a setup.cfg switch to use the system wcslib rather than the included one.

I also plan to do (c) for expat, I just haven't got around to it yet.

PR #302 added an option to disable legacy shim building.  You're 
suggesting here that it would also be nice to have something that 
*forces* legacy shim building?  That should be easy enough to do 
following the pattern laid out in #302.  Just wanted to confirm that 
adding a `--enable-legacy` commandline arg to setup.py that would always 
build the legacy shims would be helpful here.
