Merge branch 'cf/wrapper-bsd-eloop'

The fallback implementation of open_nofollow() depended on
open("symlink", O_NOFOLLOW) to set errno to ELOOP, but a few BSD
derived systems use different errno, which has been worked around.

* cf/wrapper-bsd-eloop:
  wrapper: NetBSD gives EFTYPE and FreeBSD gives EMFILE where POSIX uses ELOOP
