aarch64 uses 'trad' for traditional tls and 'desc' for tls
descriptors, but unlike other targets it defaults to 'desc'.

i think this is confusing.

on aarch64 mtls_descriptor should be 'desc', but we might
want to run some tests with 'trad' too for coverage (however
likely different tests than what other targets try to run with
tlsdesc).
