Not sure, but this would retain the behaviour Portage is doing now for non-Prefix, and would get the behaviour we want in Prefix. On an alternative note, there is CONFIG_SHELL (used for setting which shell to use with configure), which I think in many cases bleeds through to make, but should there be a MAKE_SHELL perhaps as well? Then the default would be pretty much ok. (We never ran into any problems forcing SHELL to bash in Prefix, but perhaps that's not a representative test for the whole of Gentoo.)
