Hauke Mehrtens cabdbc632e toolchain/binutils: backport stable patches
Add the patches with real changes from the binutils 2.39 stable branch.
I am not aware that we ran into any of these problems, but I think it is
better to take the existing stable patches.

They were exported like this:
git format-patch binutils-2_39...origin/binutils-2_39-branch
I removed the patches changing the version numbers only.

Subject: [PATCH 050/160] PowerPC64 pcrel got relocs against local symbols
Not that anyone would want to indirect via the GOT when an address can
be loaded directly with pla, the following:
pld 3,x@got@pcrel
x:
leads to "Internal error in md_apply_fix", because the generic parts
of assembler fixup handling convert the fx_pcrel fixup to one without
a symbol. Stop that happening.
* config/tc-ppc.c (ppc_force_relocation): Add PLT_PCREL34 and
assorted GOT_PCREL34 relocs.
(cherry picked from commit 49c3ed081fed6b8e2b48fdc48f805f11e4589514)
