Subject: targets: add mic_knl target to microarchitectures.json

- This is needed to support Cray machines -- we need an architecture
  mic_knl > x86_64

- We used Cray's naming scheme for this target to make it work seamlessly
  with the module-based detection sccheme on Cray.  mic_knl is pretty
  much dead, so this will be the last succh target.  We will need to work
  wtih Cray and other vendors in the future.
