Get us closer to building busybox
This change undefines __linux__ and adds APIs like clock_settime(). The
gosh darned getopt_long() API has been reintroduced, thanks to OpenBSD.

Upgrade cosmopolitan gcc and binutils to 2.35.2
This change upgrades to the latest portcosmo gcc patch
6728fe1a25185560603ca312a8d4352af2a4e515 which lets us avoid needing to
define __tmpcosmo_FOO constants. We're now using an appropriate binutils
version for GCC 11. The older binutils sometimes wasn't able to print
backtraces, due to not being able to find a .debug_ranges section.

This is breaking change for /opt/cosmos libraries :'( due to this weird
"error: need linked-to section for --gc-sections" that pops up.

Please run `make clean` in the monorepo before rebuilding.

Fix bugs in cosmocc toolchain
This change integrates e58abc1110b335a3341e8ad5821ad8e3880d9bb2 from
https://github.com/ahgamut/musl-cross-make/ which fixes the issues we
were having with our C language extension for symbolic constants. This
change also performs some code cleanup and bug fixes to getaddrinfo().
It's now possible to compile projects like ncurses, readline and python
without needing to patch anything upstream, except maybe a line or two.
Pretty soon it should be possible to build a Linux distro on Cosmo.

Make improvements
This change progresses our AARCH64 support:

- The AARCH64 build and tests are now passing
- Add 128-bit floating-point support to printf()
- Fix clone() so it initializes cosmo's x28 TLS register
- Fix TLS memory layout issue with aarch64 _Alignas vars
- Revamp microbenchmarking tools so they work on aarch64
- Make some subtle improvements to aarch64 crash reporting
- Make kisdangerous() memory checks more accurate on aarch64
- Remove sys_open() since it's not available on Linux AARCH64

This change makes general improvements to Cosmo and Redbean:

- Introduce GetHostIsa() function in Redbean
- You can now feature check using pledge(0, 0)
- You can now feature check using unveil("",0)
- Refactor some more x86-specific asm comments
- Refactor and write docs for some libm functions
- Make the mmap() API behave more similar to Linux
- Fix WIFSIGNALED() which wrongly returned true for zero
- Rename some obscure cosmo keywords from noFOO to dontFOO

Make considerably more progress on AARCH64
- Utilities like pledge.com now build
- kprintf() will no longer balk at 48-bit addresses
- There's a new aarch64-dbg build mode that should work
- gc() and defer() are mostly pacified; avoid using them on aarch64
- THIRD_PART_STB now has Arm Neon intrinsics for fast image handling

9f149e1de3 Elevate .text.syscall to .privileged
It turns out adding OpenBSD msyscall() origin verification broke the
--ftrace flag. The executable needs to issue raw syscalls while it's
rewriting itself. So they need to be in the same section, and that's
just plain simpler too.
