Subject: [PATCH] build-kernel: Avoid creating /lib directory

In a "merged-usr" system, `/lib` is a symlink to `/usr/lib`.  When
installing *sys-apps/systemd*, Portage checks to ensure this is the
case.  If this happens after `make modules_install` is run, `/lib` is
a directory, which causes the installation to fail.  To avoid this, we
need to explicitly install the modules into `/usr/lib` so that the
symlink can be created later.
