Alyssa Ross 3669b12f35 lib.systems: add m68k-netbsd support
m68k was recently added for Linux and none, but NetBSD also supports
m68k.  Nothing will build yet, but I want to make sure we at least
encode the existence of NetBSD support for every applicable
architecture we support for other operating systems.

Alyssa Ross 4d6a0bb966 lib.systems.parsed: add "elf" for some NetBSD archs
In Autoconf, some old NetBSD targets like "i686-unknown-netbsd" are
interpreted as a.out, not elf, and virtually nothing supports it.  We
need to specify e.g. "i686-unknown-netbsdelf" to get the right
behaviour.

Ben Siraphob f986333023 lib/systems/parse: make isCompatible description clearer and more useful
Stating that CPUs and the isCompatible relation forms a category (or
preorder) is correct but overtly technical.  We can state it more
clearly for readers unfamiliar with mathematics while retaining some
keywords to be useful to technical readers.

Ryan Burns 8ea1660b9e lib/systems: remove powerpc64 elfv1 support
I was specifying the ELF ABI using -elfv1 and -elfv2 target config
suffixes, which are nonstandard and no longer work with gnu-config.

Ryan Burns 72b3badb61 lib.systems: add powerpc64-linux
PPC64 supports two ABIs: ELF v1 and v2.

ELFv1 is historically what GCC and most packages expect, but this is
changing because musl outright does not work with ELFv1. So any distro
which uses musl must use ELFv2. Many other platforms are moving to ELFv2
too, such as FreeBSD (as of v13) and Gentoo (as of late 2020).

Since we use musl extensively, let's default to ELFv2.

Nix gives us the power to specify this declaratively for the entire
system, so ELFv1 is not dropped entirely. It can be specified explicitly
in the target config, e.g. "powerpc64-unknown-linux-elfv1". Otherwise the
default is "powerpc64-unknown-linux-elfv2". For musl,
"powerpc64-unknown-linux-musl" must use elfv2 internally to function.

Matthew Bauer d180cb9850 cc-wrapper: make machine configuration configurable
It is useful to make these dynamic and not bake them into gcc. This
means we don’t have to rebuild gcc to change these values. Instead, we
will pass cflags to gcc based on platform values. This was already
done hackily for android gcc (which is multi-target), but not for our
own gccs which are single target.

To accomplish this, we need to add a few things:

- add ‘arch’ to cpu
- add NIX_CFLAGS_COMPILE_BEFORE flag (goes before args)
- set -march everywhere
- set mcpu, mfpu, mmode, and mtune based on targetPlatform.gcc flags

cc-wrapper: only set -march when it is in the cpu type

Some architectures don’t have a good mapping of -march. For instance
POWER architecture doesn’t support the -march flag at all!

Matthew Bauer 3b32c920d5 systems/parse.nix: support eabihf
eabihf is an abi that can be used with ARM architectures that support
the “hard float”. It should probably only be used with ARM32 when you
are absolutely sure your binaries will run on ARM systems with a FPU.

Also, add an example "armhf-embedded" to match the preexisting
arm-embedded system. qmk_firmware needs hard float in a few places, so
add them here to get that to work.

Fixes #51184

Matthew Bauer a22797d356 systems: fix netbsd triple parsing

John Ericson 6a96dc0417 lib/system: Remove float from androideabi
There are two different official variations which differ in their float

`lib.systems.platforms.*android` already handles each case correctly.

John Ericson 1fe81a4bcd lib: Clean up float/fpu options
ARM ABIs now have a float field. This is used as a fallback to lessen
our use of `platform.gcc.float`. I didn't know what the MIPs convention
is so I kept using `platform.gcc.float` in that case.
