find: Allow '/' to be used with -perm for GNU compatibility

In 2005, Gnu find deprecated '+' as the leading character for the -perm
argument, instead preferring '/' with the same meaning. Implement that
behavior here, and document it in the man page.

Allow compiling usr.bin/find on Linux and Mac

When building FreeBSD the makefiles invoke find with various flags such as
`-s` that aren't supported in the native /usr/bin/find. To fix this I
build the FreeBSD version of find and use that when crossbuilding.

Inserting lots if #ifdefs in the code is rather ugly but I don't see a
better solution.

find(1): Fix -newer and -samefile to conform to POSIX[0]

By default, or with the -P flag, find(1) should evaluate paths "physically."
For symlinks, this means using the link itself instead of the target.

Historically (since the import of BSD 4.4-lite from CSRG), find(1) has
failed to refer to the link itself, at least for -newer and -samefile.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
