Well, it looks like there is not much error handling or sanity checking
in the map generation process.  If anything fails in there, or if the
output is dodgy, the libc build should simply abort, IMHO.

Your problem also reminds me that we need a /usr/bin/clang-cpp hardlink,
I will try to get that into 9.0.  Thanks. :)
