`System.Directory.getPermissions` fails on read-only filesystem

Alain O'Dea reports in an email that:
Prelude> System.Directory.getPermissions "/usr/bin/ld" *** Exception: /usr/bin/ld: fileAccess: permission denied (Read-only file system)
That seems wrong.
An access(*, W_OK) syscall by design should return EROFS on a read-only file system by specification.
This breaks Cabal on SmartOS since /usr is read-only by design and Cabal calls getPermissions "/usr/bin/ld".
