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

This script will build dependent libraries for gcc arm embedded toolchain.

OPTIONS:
  --build_tools=TOOLS   specify where to find the native build tools that
                        will be used for building gcc arm embedded toolchain
                        and related dependent libraries.  If not specified,
                        the ones in your system will be used.

			Please refer to howto-build document to find out how
			to download and deploy prebuilt native tools for 32bit
			build platform.
                        The prebuilt ones provided by arm embedded toolchain
                        team are supposed to run on 32bit build platform, thus
                        not suitable for 64bit platform.

  --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.
