You didn't mention which platform you are on.  Different UNIXes have
different linkers.

I presume you don't really mean "object files" (whose names usually
end in .o on UNIX machines), but "object libraries" (whose names are
of the form lib<name>.a, or .so, or .sl, etc.).  I presume this
because all linkers that I know of link object files in their
entirety, if they get linked at all.

Anyway, it is alright, and in your case it sounds essential, to
mention the same library multiple times on a command line.  If libone
and libtwo have some circular dependencies, it may be necessary to have

    -lone -ltwo -lone

on the command to successfully link.

Go to

http://www.gnu.org/manual/ld-2.9.1/html_mono/ld.html#SEC3

and look for 'start-group' and 'end-group' - it'll cause ld to keep
running thru the archives until it works out all dependencies.

After listing all your libraries in the link line, list them a second time.
Tacky, isn't it?
