xcompile: Add separation for architectures to improve readability

- Add bar at the top of each architecture
    - Make the architecture name and the TARCH_SEARCH to two lines
    - Add a second line at the bottom of each architecture
    - Add a comment about the two blank lines so they don't get
    accidentally removed.
