* gnu/packages/emulators.scm (unicorn): New variable.
---
Changes from v1: packaged a new -rc, which makes tests pass on ARM. Add
an input for cross-binutils, and use it while running tests. Also, the
new -rc doesn't need Python for build orchestration, so the python-2
input got dropped. The python-build-system phases hack got prefixed with
a comment referencing the core-updates patch.
