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.
