    It looks like you are re-using the same build directory for the cross-compile that you used for the original native build. The 'make' program doesn't know that you've changed toolchains, and doesn't consider the object file (main.o) to be out of date - so it doesn't try to recompile it, it just jumps straight to the link step - which fails because it's trying to link a native ELF object with foreign (mingw) libraries.

    Try executing a make clean or rm src/*.o before the make to force full recompilation.
