[gentoo-portage-dev] [PATCH] emake: explicitly set SHELL

[Fabian Groffen]

bin/ebuild-helpers/emake: force SHELL to be set

On Prefix systems /bin/sh can be anything, including very ancient.  So
ensure we're running with bash, since that's what Gentoo Linux is
expecting /bin/sh to be (by default, at least).

Provide a fallback for the (near impossible) case that we use a bash
that doesn't set BASH, or when we don't use bash at all.  This is not
expected, though, as we explicitly require bash throughout all Portage,
so we don't really care about using a non-Prefixed one, for this really
shouldn't happen.
