This broke pkgsrc/devel/bmake (which breaks pkgsrc/bootstrap too); its
configure script now detects emalloc() and adds -DUSE_EMALLOC flag to
CFLAGS, but we have the header file for libutil as <libutil.h> which is
different from NetBSD's <util.h> .  If our libutil is already close
enough to NetBSD's, just adding a symlink might be a possible solution.
