Something is going wrong with your include paths; most likely your
CFLAGS gets mangled.  The actual mkdep command line should have been
similar to (wrapped for clarity):

  CC='clang' \
  mkdep \
  -f .depend \
  -a \
  -I/usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/include \
  -I/usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/tools/clang/include \
  -I/usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen \
  -I. \
  -I/usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/../../lib/clang/include \
  -DLLVM_ON_UNIX \
  -DLLVM_ON_FREEBSD \
  -D__STDC_LIMIT_MACROS \
  -D__STDC_CONSTANT_MACROS \
  -DLLVM_DEFAULT_TARGET_TRIPLE=\"i386-unknown-freebsd10.0\" \
  -DDEFAULT_SYSROOT=\"\" \
  -I/usr/obj/usr/src/tmp/legacy/usr/include \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/Error.cpp \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/Main.cpp \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/Record.cpp \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/TableGenAction.cpp \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/TableGenBackend.cpp \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/TGLexer.cpp \
  /usr/src/lib/clang/libllvmtablegen/../../../contrib/llvm/lib/TableGen/TGParser.cpp

Are you appending or assigning to CFLAGS in make.conf/src.conf?
