x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES
either dropped or rearranged appropriately.
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
* portVersionedName contains the secondary architecture,
so using it means secondary package builds fail.
example: $portVersionedName is libwow_x86-0.0.0 when
doing an x86 build on x86_gcc2
Cleanup up the Copyright field on several of my old .OPD files.
This was done to match the example at http://www.haiku-os.org/node/2525 which
doesn't contain a comma bewtween the date and the copyright owner.
