[gold patch rfa] implement '-l:filename'

[Chris Demetriou]

GNU ld supports '-l:filename' which takes 'filename' verbatim (i.e.,
doesn't add 'lib' or '.a' or '.so') and searches for it using the -L
search path.  This patch implements that feature gold.

build natively on x86_64-linux, tested cleanly with the gold testsuite.

Ran some manual tests to verify that it worked right, too.
