tce-selftest fails on Python >= 3.10 due to deprecation warning

[sarahec]

Beginning with Python 3.10, Python prints a deprecation warning for any use of distutils. Since the selftest checks for an empty stdout to pass the test, this triggers a failure.

tcecc appears to be the culprit.

The fix is to switch to setuptools.

FAIL: test_noOpt (main.TestCompiler) Test C compilation with -O0

I found the problem, and it's a trivial fix. Line 40 of /src/bintools/Compiler/tcecc.in reads:

from distutils.spawn import find_executable

but the code was fixed to no longer use distutils. Removing this line and rebuilding solves the problem.

It's probably quicker for you to make the edit than merge a PR, but let me know if you want the PR.

Thanks @sarahec -- a PR would be great so you get all the glory in 'git blame' etc.! :)

Whoops, merged to my personal copy! Let me send this in properly.
