I would like both single and multi-threaded to be built for all 
libraries by default.  But at minimum, would like an easy way to find 
out which libraries are affected my multi-threading.  These are:

signals
filesystem
thread (obviously)

The only library I've used that isn't is

date_time

Not sure on regex, but I think its makefiles build all the possible 
versions so it isn't so much of an issue.
