Subject: [PATCH] libroot/locale: Allow global locales to be applied to the
 current thread.

I added this assertion thinking it would incorrectly override
thread locales, and that invocationns this way would be a bug.
Instead it appears that this is the expected behavior in select
circumstances.

Fixes #19896 and other recent regressions.
