treewide: sync with upstream (#10720)
* mpc85xx: add support for cpu type 8548

8540 cpu type corresponds to e500v1 core while
8548 cpu type corresponds to e500v2 core

See https://www.nxp.com/products/processors-and-microcontrollers/legacy-mpu-mcus/powerquicc-processors:POWERQUICC_HOME#powerquicc-iii-mpc85xx
and https://www.nxp.com/docs/en/application-note/AN2807.pdf .

* tree-wide: Do not use package librt and libpthread

The libraries libpthread, libdl, libutil, libanl have been integrated
into the libc library in version 2.34. it is not needed to explicitly
link them any more.

Most of the functions have been moved from the librt.so into libc.so
some time ago already.

* 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.

* toolchain/binutils: switch to version 2.39 by default

This was build tested with all core packages on all targets
successfully.

This was run tested on the following systems:
* lantiq/xrx200 musl
* sunxi/cortex53 musl
* x86/64 musl
* x86/64 glibc

Some trusted firmware arm builds needed some fixes to build with
binutils 2.39, this was merged before.

* tools: Improve diffability/maintainability

There's no purpose to squish multiple tools into a single line (and
spread those out over multiple lines). It might look 'nice' in certain
conditions, but it's annoying to maintain.

For example, but not limited to:
* adding/removing tools, causes hard to read diffs
* Duplicates are harder to spot
* Sorting can not be (easily?) automated

With this proposed change, the above annoyances go away. Inserting a new
tool can be done with a single line-change-diff, sorting can be done by
any editor (in vi, select, :sort for example) and dupes are much easier
to spot.

* rules: drop -Wno-error additional flags from default TARGET_CFLAGS

We currently enable -Wno-error=unused-but-set-variable and
-Wno-error=unused-result by default on every compile package.

While this is (relatively) unharmful, we should follow other project
direction and starts enforcing good code quality. For example the linux
kernel recently started to enforce Wall by default and clean code is
mandatory for inclusion.

Drop for good these flags and and make it mandatory to correctly handle
return values at least with a warning log if they are not strictly error
condition.

Subject: [PATCH 009/160] PR29462, internal error in relocate, at
powerpc.cc:10796
Prior to the inline plt call support (commit 08be322439), the only
local syms with plt entries were local ifunc symbols. There shouldn't
be stubs for other local symbols so don't look for them. The patch
also fixes minor bugs in get_reference_flags; Many relocs are valid
only for ppc64 and a couple only for ppc32.
PR 29462
* powerpc.cc (Target_powerpc::Relocate::relocate): Rename
use_plt_offset to pltcal_to_direct, invert logic. For relocs
not used with inline plt sequences against local symbols, only
look for stubs when the symbol is an ifunc.
(Target_powerpc::Scan::get_reference_flags): Correct reloc
handling for relocs not valid for both 32-bit and 64-bit.
(cherry picked from commit 6158b25f77db11712b84e6a4609898f2615ac749)
