I think you may have the headers set up wrong in your cross compiler
environment- math.h is defining various gcc internal functions (the
floating point stuff) to a different type than gcc expects.

That looks like some kind of conflict in libgcc (the library which gcc
links into every executable it produces).
Have you successfully used this cross compiler environment for other
applications?
