ppc32 tlsopt tests

These all were odd in that they used r13 as the GOT pointer.  That
didn't matter for the purpose of testing, but would never occur in
practice.  Also, the tlsopt5 tests could have their global dynamic
sequences optimized to initial exec, so link with -shared.

	* testsuite/ld-powerpc/powerpc.exp: Add -shared to tlsop5 tests.
	* testsuite/ld-powerpc/tlsopt5.d: Adjust.
	* testsuite/ld-powerpc/tlsopt1_32.s: Use r30 as GOT pointer.
	* testsuite/ld-powerpc/tlsopt2_32.s: Likewise.
	* testsuite/ld-powerpc/tlsopt3_32.s: Likewise.
	* testsuite/ld-powerpc/tlsopt4_32.s: Likewise.
	* testsuite/ld-powerpc/tlsopt5_32.s: Rewrite.
	* testsuite/ld-powerpc/tlsopt1_32.d: Adjust.
	* testsuite/ld-powerpc/tlsopt2_32.d: Adjust.
	* testsuite/ld-powerpc/tlsopt3_32.d: Adjust.
	* testsuite/ld-powerpc/tlsopt5_32.d: Adjust.
