--- Comment #2 from Eric Christopher <echristo at gmail.com> ---
This is fixed:

dnl If CXX is Clang, check that it can find and parse C++ standard library
dnl headers.
if test "$CXX" = "clang++" ; then
  AC_MSG_CHECKING([whether clang works])
  AC_LANG_PUSH([C++])
  dnl Note that space between 'include' and '(' is required.  There's a broken
  dnl regex in aclocal that otherwise will think that we call m4's include
  dnl builtin.
  AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[#include <limits>
#if __has_include (<cxxabi.h>)
#include <cxxabi.h>
#endif
#if __has_include (<unwind.h>)
#include <unwind.h>
#endif
]])],
[
  AC_MSG_RESULT([yes])
],
[
  AC_MSG_RESULT([no])
  AC_MSG_ERROR([Selected compiler could not find or parse C++ standard library
headers.  Rerun with CC=c-compiler CXX=c++-compiler LLVM_SRC_DIR/configure
...])
])
  AC_LANG_POP([C++])
