Reverse the order of processing object files within an executable or

shared library when invoking global constructors and destructors.
For constructors, the object files used to be processed from first
to last; now they're done from last to first.  (Destructors are done
in the opposite order, as required by the C++ standard.)  This makes
us consistent with standard gcc and egcs compilers.  It also
eliminates ordering differences between dynamic and static
executables.

Bump the value of __FreeBSD_version to 400002 to reflect this
change.
