Can't set path to tools in ~/.cabal/config

[awick]

The config file for cabal-install lets me set all sorts of useful paths, except for the non-compiler tools. In other words, there's no config file mapping for the --with-PROG or --PROG-options flags, which would be really convenient.

(At least, when I tried the obvious versions, it didn't work. Maybe missing docs somewhere?)

Hi -

The (now) attached patch set implements the behavior we were looking for, but probably does it in the wrong way. Specifically, I couldn't figure out an easy way to use ProgramConfiguration? to carry the information around such that the right flags could be added during load and spit out during use. So I added another data structure and used that.

Hopefully either not using ProgramConfiguration? was the right thing to do, or these patches will help in doing it the right way.

The patches apply cleanly to cabal-install 0.6.0.

Sigh, I wish trac let one search for tickets with patches so things like this would not get lost. :-(

This would be particularly useful for negating the new ghc default that -rtsopts is needed to do any profiling or tracing.
