Subject: [PATCH] Add ToyOS operating system

ToyOS is an operating system written from scratch in Rust, targeting
x86-64 (https://github.com/Japabu/toyos). It uses the standard System V
calling convention on x86-64, so it is registered alongside the other
SysV platforms in default_calling_convention().
