[PATCH] D46452: [sanitizer] Don't add --export-dynamic for Myriad

Herald added a subscriber: llvm-commits.

This is to work around a bug in some versions of gnu ld, where
--export-dynamic implies -shared even if -static is explicitly given.
Myriad supports static linking only, so --export-dynamic is never
