Subject: [PATCH] tools/psl.c: Fix build on Windows

localtime_r() is not available on Windows but a more-secure variant
of localtime(), localtime_s() is provided on Windows.

Define localtime_r() on Windows as its arguments are reversed as compared
to localetime_s(), to achive more or less the same purpose.
