Indeed I didn't know about it. :)  However it's not necessary to add it 
specially nowadays.  It configures its own subdirectories manually, and 
all-utils is always invoked if you execute from the src tree or a 
combined tree.

So mt-mep can go.

Not sure about that.  For sure, people are using in-tree GMP.

What should go, is the code in the toplevel configure to pick default 
paths for gmp, cloog, ppl and whatnot.  The logic should reside in the 
GCC subdirectory only.
