Usage: $0 [--skip_steps=...]

This script will build dependent libraries for GNU Tools Arm Embedded toolchain.

OPTIONS:
  --skip_steps=STEPS    specify which build steps you want to skip.  Concatenate
                        them with comma for skipping more than one steps.
                        Available step is: mingw32.
