Sweet!  I've got my environment working using this shell wrapper:

#!/bin/sh

export PATH="$HOME/src/ghc/inplace:$PATH"

case "$1" in
	install)
		shift
		cabal --config-file="$HOME/.cabal-nto-qnx-i486/config" install --with-gcc=i486-pc-nto-qnx8.0.0-gcc --configure-option=--target=i486-pc-nto-qnx8.0.0 --configure-option=--build=i686-linux-gnu --configure-option=--host=i486-pc-nto-qnx8.0.0 --hsc2hs-option=--cross-safe --hsc2hs-option=--cross-compile "$@"
		;;
	*)
		cabal --config-file="$HOME/.cabal-nto-qnx-i486/config" "$@"
		;;
esac

Can I move any/all of those switches into the config file?  None of them 
really seem to fit in the listed config options.
