Comment:

 llvm-5.0 has a universal variant, and builds universal just fine and dandy
 -- however, it is only enabled to build universal as i386/x86_64, as
 PowerPC llvm-5.0 is broken and so it is not enabled in the main MacPorts
 repo.

 Most of what you added is not used for the llvm-5.0 branch -- it was used
 for an older llvm build that built with autotools and is no longer used.

 Someday, if Iain or somebody else actually fixes llvm-7.0 (or whichever)
 to actually work properly, then perhaps some kind soul might properly fix
 a build for PowerPC that might be accepted into MacPorts, once it is fully
 tested and vetted to work.
