this is the only example that I could find:
I.e. you can have an 'Archs' field in DESCRIPTION, and apparently you
can set that to 'i386' or 'x64' or both.
I don't know what OSes support this field, and this package hasn't
been updated for a while, so I am not 100% sure, but this definitely
seems like the proper way to declare a 64-bit only package.
