perl: Switch to split configuration files

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.
