gnu: ld-wrapper: Ignore the .so argument following '-dynamic-linker'.

Browse source 
Reported at <http://bugs.gnu.org/20102>.

* gnu/packages/ld-wrapper.in (library-files-linked): Rename 'path+files'
  to 'path+files+args'.  Thread the reverse list of previous arguments.
  Add case for when the previous argument is "-dynamic-linker".
