Apparently, over 900 ports use MAKE_FLAGS, so I think it is worth it
mentioning MAKE_FLAGS in the guide. Currently it is mentioned among
the Special Topics: overriding lib names with SO_VERSION is the major
use case it seems, but one might also need it for a simple BUILD_TLS=yes
or BUILD_OS=openbsd etc.
