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

This script will build GNU Tools Arm Embedded toolchain.

OPTIONS:
  --build_type=TYPE     specify build type to either ppa or native.
                        If followed by keyword debug, the produced binaries
                        will be debuggable.  The default case will be
                        non-debug native build.

                        Example usages are as:
                        --build_type=native
                        --build_type=ppa
                        --build_type=native,debug
                        --build_type=ppa,debug

  --skip_steps=STEPS    specify which build steps you want to skip.  Concatenate
                        them with comma for skipping more than one steps.  Available
                        steps are: gdb-with-python, mingw32, mingw32-gdb-with-python
                        and manual.

  --threads=PROVIDER    specify the threading and synchronization provider.
                        Supported providers:
                        --threads=no     # Single-threaded mode (the default)
                        --threads=posix  # Posix threads and clocks, aka pthreads
