Can we do something to nix .MAKE.LEVEL.ENV from the MAKEFLAGS that
pkgsrc passes down to the do-build recipe?

It sounds like it's not really mk-configure's fault that this is
happening; really, it's a bug with pkgsrc running a do-build recipe
the wrong way -- in a way the package Makefile didn't even ask for.
