Consider building statically

[mattgodbolt]

We use rizzy as an easy-copyable binary at Aquatic. That works as we all agree on the Ubuntu version:

$ ldd target/release/rizzy
	linux-vdso.so.1 (0x00007ffd83470000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f040597e000)
	librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f0405776000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f0405557000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f0405353000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0404f62000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f04061cf000)

It might be worth looking at building a musl static build which ends up with a 7MB static binary.

$ rustup target add x86_64-unknown-linux-musl
$ cargo build --release --target x86_64-unknown-linux-musl
$ ls -hld target/x86_64-unknown-linux-musl/release/rizzy
-rwxrwxr-x 2 mgodbolt mgodbolt 7.0M Feb  3 19:27 target/x86_64-unknown-linux-musl/release/rizzy
$ ldd target/x86_64-unknown-linux-musl/release/rizzy
	not a dynamic executable
