[patch rfa] add --no-export-dynamic option to ld (for parity with gold)

[Chris Demetriou <cgd at google dot com>]

gold supports the --no-export-dynamic option to undo the effect of
--export-dynamic.? This patch adds a similar flag to ld.

I realize that the testsuite change is ... umm, cheap?? but it wasn't
obvious to me a better place to test this change, the test I enhanced
already tests with and without --export-dynamic, and it seems likely
that anybody releasing a new binutils is likely to test ELF support
first, so if the option magically breaks this test will be good enough
to catch it.? 8-)

built on i686-linux, tested with no failures.? (I did some manual
tweaking to make sure that the test failed if the option had no
effect, too.)
