This (as I've come to learn and respect) is a long overdue feature. 
Once you've got over the initial shock (it took me a week ...) it really 
is much much better.

- It no longer configures directories that are not needed - huge time saver!

- It can parallize configures

Sounds like Makefile.tpl (?) needs a tweak?

One case of this - bfd - was fixed.  Is this another case?

Readline was finally updated.  Again, very long overdue.  If there are 
problems, then please report them (hopefully with fixes).

I suspect that they are unknown (I didn't know about them).

If you're wondering these changes are occuring now so that, hopefully, 
there is plenty of time to catch problems such as you are finding before 
the next GDB/binutils release.

BTW, the place to report each problem is gcc@gcc.gnu.org (cc'd 
gdb-patches@).
