In reference to this: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=122304 Just wondered if anyone had a good way to detect a 64-bit platform in the context of an RPM spec file. While building for the Alpha, we've come across similar situations a couple of times, where we turn up a bug that's already patched, but it's %ifarch-ed to x86_64 or whatever or, like in this case, just checking for "lib64" being used instead of "lib". Aside from just manually updating ifarch lists for patches, is there any good way to just pull in a patch on any system that happens to be 64-bit? Of course, if there's not, that's no big deal, but thought it might be worth mentioning in case someone comes up with something brilliant. :)
