 Fix rdynamic flag and test on Windows

 The rdynamic tests and feature are marked broken on windows.
 This is because the flag used doesn't exist and the symbol lookup
 in the test did not account for platform differences in name mangling.

 This commit fixes the flag and tests for rdynamic on windows.

 Test Plan:
 make TEST="rdynamic"

 on both x86 and x86_64
