devel/cabal changes

Hi,

While playing with haskell port, I saw some part of devel/cabal module
which could be changed.

- set ONLY_FOR_ARCHS only conditionnally

- MODCABAL_BUILD_TARGET and MODCABAL_INSTALL_TARGET should be public
to permit overriding do-build/do-install and still use the variable

I checked that current port using devel/cabal doesn't changed.

Comments or OK ?
