We currently only check driver Wl options and don't check for the plain
-b, -Xlinker or other options which get passed through to the linker
when we decide whether to run llvm-nm --export-symbols, so we may run it in
situations where we wouldn't if the user had used the equivalent
-Wl, prefixed options.

If we run the export list utility when the user has specified an export list,
we could export more symbols than they intended.
