The only thing that would make much of a performance difference, I

built-in make functions like wildcard, if, etc.
One other thing could be a significant performance win: if we could use GNU
'make -j' to run most of the guts of the 'configure' script in parallel.
Waiting for 'configure' to finish is something that slows me down a lot;
often times 'configure' takes longer than the subsequent 'make', simply
because 'configure' is inherently sequential.
The challenge here is that a considerable part of configure scripts
depend on decisions which were made before. There is no dependency
information currently in configure scripts.
