I tried it, but found, that a more recent version of cmake and ninja is required than those provided with ubuntu 22.04. With those updated, the tests pass. I checked the logs of the buildkite run and I can see the picolibc tests are run with older versions of cmake and ninja. I am not enabling the module tests in `Armv7M-picolibc.cmake` for now.

The patches to make modules work with older CMake versions have been reverted. I expect I can reland that patch soon. After that you can rebase this patch on main again and we can test it again.
