  [SystemZ][z/OS] Relax check for additional symbols in PR section

The current check in `emitLabel()` is too strict. Inside a PR, there
cannot be no other external visible label. However, temporary labels
which are used e.g. for calculating offsets can be emitted.
A situation in which this occurs is the emission of the DWARF EH
tables, in which a temporary symbol (with an empty name) is emitted
at the begin of the table, causing an error message.
This change limits the error to non-temporary labels.
