DISCLAIMER: I'm not that familiar with cross-compiling BUT...

I think in general cross compiling from windows to linux is a bad idea.
Most distro's prefer to use the system installed libraries to build with
and link to, which you will not be able to do which pretty much leaves a
100% static build.

If you really want to do it then take a look here:
