+Since we have interest in an eventual Alpha port, it seems good to add this
+patch to our patchset now. The original patch comes from Gentoo, and like
+them, we would like to see packages behave consistently across our various
+architectures.
+
+Original Gentoo patch content follows.
+
+--
+
+Set the default behavior on alpha to use -mieee since the large majority of
+time we want this (bad/weird things can happen with packages built without
+it).
+
+To satisfy those people who may not want -mieee forced on them all the time,
+we also provide -mno-ieee.
+
+Patch by Mike Frysinger <vapier@gentoo.org>
+
+Note: upstream doesn't want to take this due to long standing behavior, and
+because it'd make behavior across OS's inconsistent:
+ https://gcc.gnu.org/ml/gcc-patches/2003-07/msg02144.html
+
+This makes sense for upstream, but Gentoo is more concerned about packages
+behaving the same across arches under Linux.
