  Sometimes using just a few simple glibc functions can inadvertently pull in a whole boatload of other dependencies.  Does
compiling with -fno-exceptions help?

  Otherwise you're just going to have to look at the output of the linker map where it shows which symbols caused which other
symbols to be pulled in and figure it out.  Is there a sprintf() call somewhere you could leave out, for instance?
