Add build-extra-platforms setting
This allows specifying additional systems that a machine is able to build for. This may apply on some armv7-capable aarch64 processors, or on systems using qemu-user with binfmt-misc to support transparent execution of foreign-arch programs. This removes the previous hard-coded assumptions about which systems are ABI-compatible with which other systems, and instead relies on the user to specify any additional platforms that they have ensured compatibility for and wish to build for locally. NixOS should probably add i686-linux on x86_64-linux systems for this setting by default.
