Subject: [PATCH] Many developers run with userland != to kernel.  While this
 isn't supported, it usually works for months at a time.  Allow these people
 to override the OSRELDATE of their installed world when things don't match
 and the exact OSRELDATE matters and is different than the kernel.  Now that
 Makefile.inc1 depends more and more about which date you have to optimize the
 pieces it builds, it may be necessary to pessimize things if its guesses are
 wrong.

If OSRELDATE is already set, we won't fork the sysctl to find out what
the kernel's date is.

Developers on IRC suggested that they run mismatches all the time as
well.
