"freebsd" and include the major version. Set target_hw to x86 for
i386, x64 for amd64, and ${ARCH} on all other platforms. Update the
comments to match reality.
To enable this for a particular port, add "cpe" to the USES list and
optionally define CPE_VENDOR, CPE_PRODUCT etc. if the defaults are not
correct (they should be in most cases).
