This patch, taken from
<https://git.busybox.net/buildroot/tree/package/gcc/5.4.0/840-microblaze-enable-dwarf-eh-support.patch>
and with a few formatting cleanups and an update for the removal of
gen_rtx_raw_REG, enables DWARF EH support for MicroBlaze.
This is needed for building glibc with a compiler that includes shared
libgcc; right now all glibc builds for MicroBlaze are failing with my
bot for lack of this support. (It's dubious if we should have glibc
ports at all where required support is missing in FSF GCC.)
Tested building glibc with build-many-glibcs.py. I have *not* done
any other testing or any execution testing for MicroBlaze.

libgo: build with -Wa,-nH if possible on Solaris
By default the Solaris assembler records the required hardware
capability in the object file. This means that the AES hashing code
breaks on systems that do not support AES, even though the code uses a
runtime check to only actually invoke the AES instructions on systems
that support it. An earlier fix for the problem only fixed the shared
library, not the static libgo.a. Fix the problem for real by using an
assembler option to not record the hardware capability.
For GCC PR 78978.
