This is an internal method that returns path to a library which
should be put on the linker command line I<after> the external libraries
to be linked to dynamic extensions. This may be needed if the linker
is one-pass, and Perl includes some overrides for C RTL functions,
such as malloc().

=head1 NAME
ExtUtils::MM_OS2 - methods to override UN*X behaviour in ExtUtils::MakeMaker
=head1 SYNOPSIS
use ExtUtils::MM_OS2; # Done internally by ExtUtils::MakeMaker if needed
=head1 DESCRIPTION
See ExtUtils::MM_Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.
