The compressed objects will be included in many binaries (and I guess
that most users will never ever use them...). They should therefore be
as small as possible.
But the approach of simply including the code for compression is a good
one. It solves the zlib-detection-during-build problem and the .text
size of the encoding code does not matter given that bin2c only exists
on the dev machine. I'll implement this.
