Comment (by igloo):

 Don't people with shared `$HOME`s already have ways to deal with this,
 e.g. passing `--prefix=~/i386` for configure/make programs, with
 `~/i386/bin` in their path? Wouldn't it make most sense for them to do the
 same for Cabal programs?

 And if they are doing something like that, then we won't know whether they
 want `$arch` to be `i386`, `i686`, `x86`, or something else.
