Clang Clang Clang Went the Buildbots

[Fred Wright]

It probably wasn't a good plan to push simultaneous updates to every clang 
version in sight.  I imagine the buildbots are still struggling to catch 
up, and meanwhile users doing "upgrade outdated" are stuck doing long 
builds from source.  My MacBook Pro alone took almost 19 hours, and the 
whole process took over 24.

BTW, on 10.11, upgrading clang-14 wants clang-11, which fails to build, 
apprently due to building something for i386 and failing to link against 
the non-uiniversal libxslt.
