[PATCH] D18501: Fix <cmath> compilation on FreeBSD

Yes, this was indeed the wrong include order.  During the latter stages of FreeBSD's buildworld, the compiler is invoked with `-nostdinc++`, but `/usr/include` was put before the libc++ include directory, `/usr/include/c++/v1`.  So as @rsmith remarked, the system's `math.h` was found before the one from libc++, causing the complaints about missing declarations.
