Re: -r321371 amd64 -> powerpc64 cross build: lldb.full link fails with: c++: error: linker command failed with exit code 1, -B/usr/local/powerpc64-freebsd/bin/ in use

[The lldb problem is a:

lldb_private::AppleObjCRuntime::GetFoundationVersion()

reference via Cocoa.o in liblldb.a . See below.
Sorry that sometimes I'm having to go back and
later find and report more details because of
other things going on here. But this likely
will continue for some of my preliminary
reports.]
