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 <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.

Subject: [PATCH] gcc/config.gcc: sh-*: Disable sysroot-suffix (PR42947)
sh-* is a multilib target. It is also one of 2 sysroot-prefix targets.
Unfortunately two options do not mix well. Attempt to use default
multilib flavour always prepends sysroot-prefix.
