AMD64 package help needed

[Michael Schwendt]

Occasionally, there are reports about src.rpms which fail to rebuild for
x86_64, e.g. Gtkmm 2:

  https://bugzilla.fedora.us/show_bug.cgi?id=1421

To know whether a version upgrade fixes this, requires that someone
with an AMD64 system attempts at rebuilding it prior to release. Else
the release process looks like

  QA for x86 
   -> PUBLISH for x86
   -> bug report about x86_64
   -> fix and prepare update
   -> QA for x86 (regression testing)
   -> if fix needs modifications, try on x86_64 again
   -> PUBLISH for x86 and x86_64

and results in increased work for the packagers and reviewers.

If there are people from the Fedora for AMD64 community who read this,
please join and help!
