   4 Subject: [PATCH] Pass empty CFLAGS on invocation of libfdt/setup.py
   5
   6 When building u-boot tools in cross-build environment CFLAGS environment
   7 variable set up for target is taken into an account when building code
   8 for host. Make it empty on invocation of python.

  11
  12   cc1: error: unrecognized command line option "-mlongcalls"
