There=92s no easy way to force this, although yo= u might get some milage out of WMAKEENV options, but I think we bake most= of the where to look for things options into the binaries.

Instead of make buildenv to get an interactive shell you can do something like BLDENV=3D`${MAKE} buildenvvars` chroot buildchroot/ "env -i $${BLDENV} cd /usr/src/somewhere && \ make all install"=20 -- Ian
