execution test

That is a completely irrelevant observation.  A lot of testcases got
disrupted by the removal of wide character functions, causing link errors,
or the tests being skipped in the first place when some capability test
failed.  So any pre-existing execution failures would get masked.
Re-enabling wide character support makes the execution tests run again,
so the old execution failures come back.

We need to decide first if --enable-newlib-nano-formatted-io should or
should not remove support for wide character handling.
Then we can look at individual test failures.
