[zorg] Limit clang-sparc64-linux-multistage to Sparc target

[glaubitz]

Summary

This helps reducing the build time a little as we are interested in the Sparc target only anyway.

Please let's wait with merging this as I need to make sure it doesn't break the testsuite.

Please merge https://reviews.llvm.org/D90530 first, I'll update this revision afterwards.
