commit: https://git.buildroot.net/buildroot/commit/?id=bfea22f3321b902c597416061dab079096bc77ec
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.

This fixes the following build errors when cross-compiling for xtensa:

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