Just happenstance. I had clang and llvm 3.8 installed previously. But 
PostgreSQL needs llvm 3.9, so I installed that, but I didn't think to 
install clang 3.9.

To add to the story: I installed clang 3.9, but I still got the same 
error. I now had both clang 3.8 and 3.9 installed, but /usr/bin/clang 
still pointed to clang-3.8, so autoconf still picked that up. Only after 
removing clang-3.8 altogether, it started working.

For the record, this is on a pretty normal Debian Stretch installation.
