Audrey Dutcher 77ff1492aa expect: Fix build on native FreeBSD
- Enable-cross-compilation.patch hardcodes several linux defaults.
  Vendor the patch and improve so it does not do this.

- Make the darwin compat patch also help out for FreeBSD

- Add freebsd-unversioned.patch, which removes some seemingly broken
  code from the FreeBSD configure path.

Subject: [PATCH] enable cross compilation for expect
This patch was created by running ./configure on a modern Linux machine
and inserting the results into the cross compilation section of
each AC_MSG_CHECKING that bombed out with an error.
Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com>

The original patch, and description above, is originally from
https://github.com/buildroot/buildroot/blob/master/package/expect/0001-enable-cross-compilation.patch
This patch has been further modified to not hard-code Linux assumptions.
