It's a fairly good assumption that if someone sets ACLOCAL_FLAGS, then
they will set it correctly. Following is the code snippet from 
GTK+'s autogen.sh that checks the no-ACLOCAL_FLAGS case.

I've Cc'ed Shawn Amundson who wrote the test, but I think it should
be fine to steal in any case ... it's not doing anything 
non-obvious.
