Re: PowerPC64 __tls_get_addr_opt stub .eh_frame fix

The modified test failed on some powerpc targets due to differences in
default hash style.  If the default hash style is both, then more
sections are created, bumping section ids.  Section id is used in stub
symbols and although the test is careful to not depend on id in
labels, the stub hash traversal order changes when stub names change.
That lead to the stubs being emitted in a different order and thus not
matching expected output.

	* testsuite/ld-powerpc/powerpc.exp: Run tlsopt5 with hash-style
	specified.
