While setlocale() is present, musl currently doesn't provide a suitable implementation.
It'll silently accept every locale, even if not present at all, defaulting them
to C.UTF-8. This will confuse applications as well as our testsuite(see lib/locale.t).
Even if a locale does exist, it's effects will not apply to an extent that will
satisfy many applications.
Avoid further mischief here and just disable setlocale() for now.

This replaces the previously used collection of configuration files for every single
architecture in conjunction with hacky overrides, which became an increasing burden to maintain.
Fixes a number of outstanding bugs and oddities, with the most important one being the
previously wrong signal order(as shown by ext/POSIX/t/sigaction.t).
See files/perlconfig.pl's POD and files/README.config for details.
