Option for stripping binary

[torkleyy]

I think it would be helpful to have an option for stripping the binary (probably as default in release mode) because executables often get much smaller.

I would like to have this as well. See also #4122.

(ugly) workaround is:

RUSTFLAGS='-C link-arg=-s' cargo build --release

#4122 (comment)

Possible solution is the recently released cargo-strip

That appears to just call strip, which may not always be what you want (you may want x86_64-linux-musl-strip, for example).

@dewyatt I'd suggest opening an issue with cargo-strip as that may be a use case that wasn't considered.

For the record, I was slightly confused why my release binary had 3 MB of size, and I found debug info inside of my release binary. After strip the size is just 500 KB.
