  [llvm-link] fix linker behavior when linking archives with --only-needed option

This patch fixes linker behavior when archive is linked with other inputs
as a library (i.e. when --only-needed option is specified). In this case library
is expected to be normally linked first into a separate module and only after
that linker should import required symbols from the linked library module.
