micropython uses -Wfloat-conversion since version 1.13 and
https://github.com/micropython/micropython/commit/30840ebc9925bb8ef025dbc2d5982b1bfeb75f1b

This will result in the following build failure with gcc 4.8:
arm-none-linux-gnueabi-gcc: error: unrecognized command line option '-Wfloat-conversion'

To avoid this build failure, set CWARN to an empty value moreover, while
at it, move some duplicated variables under MICROPYTHON_MAKE_OPTS

Fixes:
