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 [1].

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.
