[feature request] add function strtoull_l and similar

I'm building libc++ against musl, it requires strtoull_l and similar
functions in order to implement C++ header <locale>. I have no idea whether
these functions are standard or glibc extensions.

Thanks

You can just redirect them to plain strtoull, etc.; musl does not
support radix separators other than '.' so there's no need for passing
a locale argument. The GNU/BSD _l variants will probably be added at
some point in the future (ignoring their locale argument) but fow now
it's probably just easiest to work around their absence.

Sory - I gave link without checking whether ellcc really uses it.

If it's really necessary, you can import this function eg from FreeBSD:

The function in question was the nonstandard strtoull_l, not strtoull.
In the case of the former, attempting to import it from FreeBSD would
definitely not be the right solution; you'd have to import a large
part of the FreeBSD locale framework it depends on, in which case
you'd be giving very inconsistent behavior with the rest of musl, or
you'd have to strip the code that's using the locale and make
strtoull_l ignore it, in which case the outcome would be identical to
using the existing version in musl, but with a lot of duplicate code
added.
