Differences from original release:
- the most recent components used where possible, core components directly from HEADs of repositories
- compiled with recent toolchain, which results in much better performance on host system
- libstdc++ with disabled exceptions (as in size-optimized libraries that come in "nano" set) and disabled verbose error
  output (--disable-libstdcxx-verbose)
- newlib with different configure options (--enable-newlib-register-fini removed, --enable-newlib-io-c99-formats,
  --disable-newlib-atexit-dynamic-alloc, --enable-newlib-reent-small, --disable-newlib-fvwrite-in-streamio,
  --disable-newlib-fseek-optimization, --disable-newlib-wide-orient, --disable-newlib-unbuf-stream-opt,
  --enable-newlib-global-atexit)
- all libraries are not stripped - debugging them is possible
- lack of some text files and documents
- disabled multilib for ARMv8-M architectures
