Subject: [PATCH] Add basic support for FreeBSD.

This commit adds basic support for FreeBSD by adding an
`alias_freebsd.go`.
The only supported backend is the `file` backend when compiled for
FreeBSD.

We also add some `.gitignore` entries for vim backup files and add
entries to the `Makefile` to compile freebsd-{389,amd64} binaries.
