Your problem here is that you are trying to use gcc (that is probably an
x86 gcc) with options for an ARM gcc. It does not work. You have to
ensure that the build system uses your cross-compiler.

I have no idea. But I can tell you that you do not need to patch
anything. It should work out of the box.
