Introduce new fatcosmocc command

Browse source 
This new script is an alternative to the `cosmocc` command. It's still a
work in progress. It abstracts all the gory details of building separate
copies of your executable and then running the apelink.com program.

```
If you want to cut out the bloat and instead make your executables as
tiny as possible, then the monorepo supports numerous build modes. You
can select one of the predefined ones by looking at
[build/config.mk](build/config.mk). One of the most popular modes is
`MODE=tiny`. It can be used with the `cosmocc` toolchain as follows:
If you don't want rich runtime features like the above included, and you
just want libc, and you want smaller simpler programs. In that case, you
can consider using `MODE=tiny`, which is preconfigured by the repo in
[build/config.mk](build/config.mk). Using this mode is much more
effective at reducing binary footprint than the `-Os` flag alone. You
can change your build mode by doing the following:
```sh
cd /opt/cosmo
make -j8 MODE=tiny toolchain
export MODE=tiny
cosmocc --update
```
Now that we have our toolchain, let's write a program that links less
surface area than the program above. The executable that this program
produces will run on platforms like Linux, Windows, MacOS, etc., even
though it's directly using POSIX APIs, which Cosmopolitan polyfills.
We can also make our program slightly smaller by using the system call
interface directly, which is fine, since Cosmopolitan polyfills these
interfaces across platforms, including Windows. For example:
```c
// hello2.c

Let's say you only care about Linux and would rather have simpler tinier
binaries, similar to what Musl Libc would produce. In that case, try
using the `MODE=tinylinux` build mode, which can produce binaries more
on the order of 4kb.
But let's say you only care about your binaries running on Linux and you
don't want to use up all this additional space for platforms like WIN32.
In that case, you can try `MODE=tinylinux` for example which will create
executables more on the order of 8kb (similar to Musl Libc).

# the difference is that (1) your binaries will be linked with the
# cosmopolitan c library, rather than your system specific tooling
# and (2) they'll be fat ape executables that run on the platforms
#
# * amd64
# + linux
# + macos
# + windows
# + freebsd
# + openbsd
# + netbsd
# * arm64
# + linux
# + macos

# - you need to use linux to build your binaries currently, but you
# can scp and distribute the output files to the above platforms!

/**
* @fileoverview Command for printing `-march=native` flags.
*
* In recent years (2023) compilers have decided to remove support for
* the `-march=native` flag, even on x86. That's unfortunate, since as
* we can see below, grokking all the various microarchitecture is not
* something a compiler should reasonably expect from users especially
* not for a flag as important as this one, which can have a night and
* day impact for apps that do scientific computing.
*
* This is a tiny program, that makes it easy for shell scripts to get
* these flags.
