Subject: [musl] Implementation of built-in locale only allows for 'C.UTF-8' and fails with just 'C'

Hi,
I run into a problem compiling a C library into WASM using emscripten,
which in turn uses libmusl.
The library calls 'locale_t __newlocale(int mask, const char *name, locale_t
loc)' with name being "C".
the implementation in musl calls __get_locale() with val being "C":
https://github.com/emscripten-core/emscripten/blob/2bca083cbbd5a4133db61fbd74d04f7feecfa907/system/lib/libc/musl/src/locale/locale_map.c#L44
-- extracted from locale_map.c:
int builtin = (val[0]=='C' && !val[1])
> || !strcmp(val, "C.UTF-8")
> || !strcmp(val, "POSIX");
> if (builtin) {
> if (cat == LC_CTYPE && val[1]=='.')
> return (void *)&__c_dot_utf8;
> return 0;
> }
If I understand that code correctly, it will return 0 (fail) if the name is
just "C" and not "C.UTF-8".
Is this the intended behavior? (note that glibc and others do NOT require
the .UTF-8, a simple 'C' works just fine and many existing code relies on
that).
Thank you.
