packages from a single port. LOOP_VAR is the name of the variable
and LOOP_OPTIONS is a space-separated list of values it should
take. When these are set, the target "package-loop" will go
through a clean and package loop for all the options. The
"package-loop" target is defined as "package" when LOOP_VAR is not
defined, so if you are in the business for building packages, you
should use "package-loop" all the time. (This target is added to
bsd.port.subdir.mk too.)
Also, the "describe" target prints out multiple lines so that all
options will go into the INDEX. (In other words, if you define
these variables, INDEX is going to look real silly if you don't
put ${${LOOP_VAR}} in PKGNAME.)

(2) Turn off regexp support for LIB_DEPENDS. It is a fixed string of
the form <NAME>.<VER> now.
Tested by: several rounds of complete package builds
(3) Check checksum even if NO_EXTRACT is defined.
(4) Cosmetic fix for message in MANUAL_PACKAGE_BUILD case.
