I like this.  Then just set an environment variable, GCCDIR, and set it to
point to the appropriate dir.

If we could have directories that were "logical unions" of other
directories, like the Hurd was supposed to have, this would be so easy.

Someone said something about /opt being a ghetto in Linux.  Well, what
better place?  Most major commercial unix's have it. Its Not a Bad Thing
(tm). Its Just Whats Needed.  Wabi already goes in there.

Just as a note: Someone probably IS going to end up writing a symlink
switcher.  But I like the /opt solution.  Its much cleaner.
