[I apologize for the delay.]

The test is assuming that locale "@colStrength=primary" is valid for
ICU but invalid for libc. It seems that on that platform, setlocale()
is accepting it?

If some libc implementations are too permissive, I might need to just
disable this test. But if we can find a locale that is consistently
acceptable in ICU but invalid in libc, then I can keep it... perhaps
"und(at)colStrength=primary"?
