patch for PR/17684

[Jan Beulich]

H.J.,

you appearantly applied the change to all target make file fragments
that have SHLIB_LINK. For NetWare (and its NLMs) this is inappropriate,
however, because the filename specified as output filename is also
embedded in the generated image; the OS (under certain circumstances)
checks that filename and embedded name match, which they can't with the
change you applied.

Thanks, Jan
