Perhaps we could compress these paths down to:

  tests/tcg/benchmarks/foo.c
  tests/tcg/benchmarks/bar.c

and then we can also ensure they are built using the existing TCG tests
cross compile framework.

As external URLs are potentially unstable I think we want to distil the
details into a rst do in docs/devel/
