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

[Dimitry Andric via cfe-commits]

dim added a comment.

Note that these compilation errors came up specifically because @bdrewery is doing cross-compilation of FreeBSD with recent versions of gcc.  Apparently clang does not give the same errors on these undefined identifiers, but I'm not entirely sure why not...
