Don't configure BFD or TK or their dependencies on darwin

[Geoffrey Keating]

BFD has not (yet, he says hopefully) been ported to Darwin's mach-o
format, and TK doesn't work because although there is a macos port the
sources version doesn't have the right Makefiles.   So, this disables
them allowing a combined-tree build on Darwin to work.  It also
disables everything that relies on BFD or TK, which is a lot.

Tested by running a combined-tree build on powerpc-apple-darwin6.0.

Any objections to this patch?  I'll wait until tomorrow to give people
time to comment.
