Log Message:
PR lib/58674 (and I suspect, several others)

Stop expecting strptime(3) in the tools build, it is an XSI
function, and the tools builds do not set up the environment
to expect XSI functions to be available.

This means dropping support for the -f option in the tools date
(which shouldn't matter, -f sets the format for the string used
to set the time, which the tools date does not support), and
open coding parsing for the -d option in the tools build.

There should be no changes to the date(1) that is installed in /bin

As a (minor) benefit, the tools -d support has become somewhat
more flexible than the previous simple strptime() implementation
allowed, and also does better error checking (no more Feb 30 etc).

Note: no change to the usage message, if -f is passed to the tools
date it will elicit a usage which says that -f is supported...
(that's just laziness...)
