Use -std=gnu89 to fix the build with clang-16

This is ancient GNU software that tends to break whenever clang adds
more warnings about deprecated features in new languages versions or
turns them into errors. Using -std=gnu89 (the defaults for base-gcc)
for those packages means we'll probably avoid most new warnings, errors,
and possible miscompilations when updating clang.

Recommit the switch to use llvm-strip on architectures that use ld.lld.

ok naddy@, sthen@

Revert previous commit (but leave the man page around); llvm-strip behaves
differently on files that are hardlinked and this is tripping up ports.

requested by naddy@

The binutils strip damages GNU_RELRO on binaries linked by ld.lld on at
least amd64. Fix this by switching to the llvm strip on architectures
that use ld.lld.

binutils-2.17 does not have ld or gas available for the aarch64, powerpc64, or
riscv64 family of platforms, so we don't try to build there.

However we mis-nested the arch check, causing some unintended side effects,
most notably installing binutils-2.17's ar(1) which overwrote the
intended llvm-ar(1).

Fix the if nesting so it only applies where intended.

tested on aarch64 by me, powerpc64 by gkoehler@, and riscv64 by jca@

Avoid errors about clang13-only options here, to ease transition

As pointed out by deraadt@ we can do better than ask people to follow
instructions. Note that you still need an up-to-date clang if you
update your kernel Makefiles, as those use clang13-only options.

Also -Werror doesn't bring much in binutils context. It's an outdated
codebase with lots of warts, which frequently breaks due to -Werror
during clang updates.

avoid build race condition: our make has an "expensive job" heuristic
which means we do stop creating other jobs as soon as we run something looking
like "make" to avoid unwanted recursion, so you would never hit that.

But in binutils-2.17, the developers changed all/info to do recursive makes
with some of the same dependencies. Calling both at the same time becomes
an obvious race, and should be fixed for no other reason than correctness.

Add infrastructure to install lld as the default linker. The old GNU linker
will be installed as /usr/bin/ld.bfd on supported systems. This allows
users to fall back on the old linker by using the -fuse-ld=bfd option on

Switch armv7 to use lld as the default linker. On arm64 we already use lld
as the default linker. Other platforms will keep using the GNU linker for
now.
