[patch] libc/locale/setlocale.c: remove unused arg

[Sébastien Marie]

Hi,

I start reading libc/locale code in order to understanding it.

Here a patch to remove an unused argument "isspecial" from static
function "load_locale_sub".

The function is called once, with isspecial=0, and the argument isn't
used in function's body.

Any comments ?
