This should fix the std/text_encoding/* FAILs that Iain sees on darwin.
I assume it will make it work for FreeBSD too.
I won't push this until I hear it works for at least one of those.
Tested x86_64-linux.

The <xlocale.h> header is needed for newlocale and locale_t on these
targets.
libstdc++-v3/ChangeLog:
* acinclude.m4 (GLIBCXX_CHECK_TEXT_ENCODING): Use <xlocale.h> if
needed for newlocale.
* configure: Regenerate.
* src/c++26/text_encoding.cc: Use <xlocale.h>.
