Default optimization of rust ports

Hi,

Since there is work and general interest regarding optimization would it 
make sense to make LTO and possibly CODEGEN_UNITS=1 opt-out while we 
still have a fairly manageable amount of ports using Rust?

Just an idea I got from looking at 
https://git.alpinelinux.org/aports/tree/testing/b3sum/APKBUILD#n23

Best regards,
Daniel
