It was my pick... and I recognize there is no good, universally accepted
place, to put such things short of mixing them into the
/usr/local/{bin,lib,share} trees.

This convention seems to be permeating the Haskell ecosystem. In
particular, the new cabal layouts use it. I decided to keep it. Including
the architecture is nice for those developers that want to keep both 32-bit
and 64-bit installed for testing. The melding of the platform with the ghc
space was because it really isn't possible to replace one keeping the
other, and others didn't like the complication of two trees (though that is
what we have on OS X).

Sure. Pull requests welcome!

I wouldn't want to rely on that as I don't think one could expect it to be
in most linux distributions base package set.
