When building u-boot tools in cross-build environment CFLAGS environment variable set up for target is taken into an account when building code for host. Make it empty on invocation of python.

cc1: error: unrecognized command line option "-mlongcalls" cc1: error: unrecognized command line option "-mauto-litpools"
