[Valgrind-developers] Add localtime() to internal ignore list for OS X

[Jeffrey W. <nol...@gm...>]

I'm catching a finding on a call to localtime() on OS X 10.8. I'm
using Valgrind 3.11.0, and I compiled with -O1.

I think Apple dynamically allocates the tm struct rather than making
it statically allocated. I see others have encountered the same issue
on OS X (cf., http://stackoverflow.com/q/10105181 and
http://stackoverflow.com/q/15613511).

Please consider ignoring leak findings for localtime() under OS X.
