You can check my script to build a complete toolchain, including newlib
in "standard" and "nano" variants.

https://github.com/FreddieChopin/bleeding-edge-toolchain

It works on Ubuntu if you install the packages mentioned in README.md.
If you have any issues using / understanding it - please let me know.
