powerpc64 11.0-CURRENT portmaster lang/clang36 gets another error: llvm-build: error: '::sscanf' has not been declared

[Nathan Whitehorn]

Which compiler are you building with? Just using the normal lang/gcc 
works for me without issue doing make install in lang/clang36. Are you 
sure you don't have any local diffs or stale files?
