Something in your make.conf is not working properly, causing mkdep to
run with gcc instead of clang.  I suggest removing the .if statements,
and simply using:

CC=clang
CXX=clang++
CPP=clang-cpp

You cannot build libc++ with g++, you must either use clang, or set
WITHOUT_LIBCPLUSPLUS.

Which reminds me that we should really put a seatbelt in Makefile.inc1
