[gentoo-catalyst] Setting make.conf variables

[Dustin C. Hatch]

I am curious what the correct way to set Portage/make.conf variables, 
besides USE, for building stages is. In particular, I'd like to know how 
to set FEATURES, MAKEOPTS, and EMERGE_DEFAULT_OPTS. I've tried setting 
them in /etc/catalyst/catalystrc, but that has the nasty side effect of 
negating entries in portage_confdir/env. Is there a better way to set these?

Regards,
