Subject: [PATCH] pony-corral: Tells hydra to use base arch instead of native

The current ponyc defaults to generative code using "native"
unless you specify --cpu on the command line. This causes
this hydra-built package to SIGILL on systems with lowlier
CPUs (many cloud VMs).

This PR ensures that corral is built in a way that the typical
stdenv use of using NIX_ENFORCE_NO_NATIVE=1.

This will hopefully fully resolve Issue #414174.
