Index: 25_all_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
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 <vap...@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.

Index: 42_all_superh_default-multilib.patch
===================================================================
The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
you have to actually list out the multilibs you want or you will end up with
just one when using targets like 'sh4-linux-gnu'.
The resulting toolchain can't even build a kernel as the kernel needs to build
with the nofpu flag to be sure that no fpu ops are generated.
Here we restore the gcc-3.x behavior; the additional overhead of building all
of these multilibs by default is negligible.
