I agree.
At the moment it's working quite well as it is, maybe we should add some
extra unexports in the main Makefile for things that are known to be
For instance on Gentoo RUBYOPT is set, and when buildroot builds
host-ruby this causes problems.
The best solution would be to unexport RUBYOPT (and RUBYLIB while at
it), i just didn't send a patch yet because i'm looking at the thread to
see how it pans out :)
