how about a repository for platform-specific configuration files? that way you only 
need the first user on each platform to figure things out, either by installing extra tools
or by modifying existing configuration files?

btw, lots of things have changed since i last built ghc, but i thought it strange that
configure used to rediscover platform-specific configuration data for each sub-project
(each running its own configure, but not seeming all that specific in what to test for).
