[PATCH 0/4] Clean up some testsuite issues

[Peter Rosin]

Hi!

This series addresses some nits in master that makes various
tests PASS where they presently FAIL.

1/4: ar-lib: ignore the verbose modifier instead of erroring out
2/4: tests: fetch the 'ar-lib' script for archiver usage
3/4: tests: fetch the 'compile' script for subdir objects
4/4: tests: do not assume the object file extension is .o

I would really like to commit 1/4 somewhere other than master,
such as on msvc, but the freshest ar-lib is only available on
master so there is little one can do to fix that cleanly. Bummer.

Anyway, ok for master?

Cheers,
Peter
