options `start' and `stop' now (unless I have forgotten any). This allows
us to call the scripts from /etc/rc.shutdown with the correct option.
The (42 or so) ports that already DTRT before are unchanged.
hanemacs and hmconv had invalid version strings (fixed).
I also got replaced AMI_VER and HANIM_VER with PORTVERSION but I
didn't touch BROWSER_VER (in netscape ports) since it was used in too
many places.
${MACHINE_ARCH}--freebsd${OSREL} is now passed to CONFIGURE_ARGS if
GNU_CONFIGURE is defined. Take the target out of CONFIGURE_ARGS of
some ports that added it explicitly; define it as
${MACHINE_ARCH}--freebsd if the port doesn't like the ${OSREL} part;
define it as something else (such as ${MACHINE_ARCH}--freebsdelf if
the port requires that; define it as an empty string if the port
doesn't like it at all.
The last might be a sign that a GNU_CONFIGURE port actually doesn't
use GNU's version of configure at all; but I don't have time to go
look at them all, we'll fix them as time goes on.
At least we've got much fewer "-unknown-"s in the tree as the result. :)
