Unrecognized '-rdynamic' flag when using swiftc linker driver

[cmcgee1024]

While using the swiftc linker driver on Linux with the following setting override from SwiftPM:

LINKER_DRIVER=swiftc

I get the following error that the '-rdynamic' is an unknown argument:

It could be related to the setting ENABLE_TESTABILITY=YES that's set in the PIF coming from SwiftPM.
