Linker diagnostics for the incorrect options .

This is really a feature of the getopt functions provided by the libiberty
library.  Note that the correct behaviour does happen if you use two dashes
instead of one:

  % ld --non-static test.o
  ld: unrecognized option '--non-static'
  ld: use the --help option for usage information

Essentially this is a user education issue.  Long options should be proceeded 
by double dashes.  Single dashes may work, sometimes, but weird effects can
also occur.
