Fix shell globbing for mingw

Why did this ever work? Hard to say...perhaps a library we linked
against was setting `int _dowildcard = -1;` somewhere and no longer
is. Apparently linking with CRT_glob.o has been the way to do this for
a very long time, and we've just been lucky that it worked all this
time.
