_doebuild_path: Respect order defined in ROOTPATH (bug 667662)
Respect the order of paths defined in /etc/env.d/*, so that
packages like llvm can rely on ordering relative to paths
defined in /etc/env.d/50baselayout since baselayout-2.6.
See: https://gitweb.gentoo.org/proj/baselayout.git/commit/?id=277e5b9e55717873b87eb541a95f4f2ae0c60a4d
