[zorg] Add solaris11-amd64, solaris11-sparcv9 builders

[ro]

Summary

I'm working to provide two Solaris 11.4 build slaves with a clang builder each, one on
amd64, the other on sparcv9. I'm still working out the details like parallelism and
max_builds, but the attached patch captures the basics, intended to be minimal.

LGTM

Further testing in the exact buildbot user environment revealed that I'd forgotten one
crucial option: clang calls the linker with Solaris ld-only options. If GNU ld happens to
be earlier in PATH at link time, this breaks the build.

Until I've figured out how to either pre-configure Solaris ld differently or make clang
work with gld, I'm forcing the right linker.
