[gentoo-dev] crossdev, distcc, and multiple toolchains... (was New global USE: crossdev)

[Jeremy Huddleston]

I'm all for the crossdev USE flag...  I think there's a lot we can do 
with it for moving away from crossdev towards a crosscompilation 
toolchain straight out of portage...

First of all, I think we should have a binutils-config package similar 
to gcc-config so we can switch between different toolchains...  then we 
can put the gcc-config and binutils-config options into 
/etc/{init,conf}.d/distcc

Additionally, it would be nice if the gcc (and in the future, binutils) 
profiles had the complete gentoo version string for the profile name:
x86_64-pc-linux-gnu-3.4.0-r6 instead of x86_64-pc-linux-gnu-3.4.0.

Can SLOT be dynamically set yet based on use flags?  IIRC, something 
like the following isn't allowed because we're not supposed to have code 
in the global section of an ebuild:

if use crossdev; then
	SLOT="${PV}-${CTARGET}"
else
	SLOT="${PV}"
fi

solar caught me commenting about crossdev stuff in #-dev earlier today, 
and it looks like I volunteered to help at putting all this together...

Does anyone have any suggestions about this?
