In theory, the libc++ headers that are part of the C++03 spec (i.e. not =
things like <stdatomic>) should work in C++98 / C++03 mode, however the =
implementation in libc++ must be compiled in C++11 mode.

To upstream this patch, the __LONG_LONG_SUPPORTED flag should be =
unconditionally set for non-FreeBSD flags in the __config file in =
libc++.  This will have no functionality change on other platforms.
