Mk/bsd.lto.mk: add global LTO support for ports

It's well known that LTO provides both performance and size benefits for
binaries.

Add preliminary, opt-in support for global LTO enforcement to ports. Ports that
provide LTO option on their own and the ones that don't work with LTO will need
to set LTO_UNSAFE in the future.
