zephyr: Build fails with gcc-arm-none-eabi-9-2019-q4-major

Describe the bug There is a Toolchain issue with gnuarmemb 9.2 (current version) under Windows

To Reproduce Steps to reproduce the behaviour: Just follow getting started and 3rd party toolchain

I installed to c:/gnuarmemb but I don’t think this should matter

Expected behavior west -b nucleo_f401re samples\hello_world should work but I get error (see below)

Impact Showstopper for new developers should be easy fixable for people with knowledge to cross compile on windows
