mpy-cross/Makefile: Also undefine MICROPY_FORCE_32BIT and CROSS_COMPILE.
mpy-cross is a host, not target binary. It should not be build with the target compiler, compiler options and other settings. For example, If someone currently tries to build from pristine checkout the unix port with the following command: make CROSS_COMPILE=arm-linux-gnueabihf- then mpy-cross will be built with arm-linux-gnueabihf-gcc and of course won't run on the host, leading to overall build failure. This situation was worked around for some options in 1d8c3f4, so add MICROPY_FORCE_32BIT and CROSS_COMPILE to that set too.
