Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch

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

-mieee).

To satisfy those people who may not want -mieee forced on them all the time,

we also provide -mno-ieee.
