#5580: Make switching GHC versions easier on Mac OS

---------------------------------+------------------------------------------
The standard .pkg installer for GHC or the platform follow the Mac OS
convention of keeping different versions in separate version folders in
the framework, with a symlink from Current to the current version.
However, the wrapper scripts (/usr/bin/ghc, runhaskell, ghci) all
explicitly mention the full path to the GHC that was most recently
installed, like
{{{
datadir="/Library/Frameworks/GHC.framework/Versions/7.3.20111017-x86_64/usr/share"
}}}
This prevents us from easily switching versions by just changing the
symlink to an older version. Could the variables in the GHC script be
changed to something like
{{{
datadir="/Library/Frameworks/GHC.framework/Versions/Current/usr/share"
}}}
so we can switch more easily?
