Just throwing this out there: I see a configure script param:
--optflags=OPTFLAGS override optimization-related compiler flags
You could tell the compiler to optimize for size rather than speed by
using -Os .
The libs may not perform as well, but that's the tradeoff. I've never
tried this, so I don't know how much of an effect it would make.
