I hope that's not what potential reviewers think!

Yes, that's because I don't intend to make -pie -static work together
(with the traditional meaning of -static).

and your PR 81295.

The fails are due to Ubuntu patches, and a testcase that is too fussy
over expected output.  Problem is that .dynamic and other sections sit
between .text and .bss, so anything like changing hash style makes
.bss move.  This patch should make the tests more robust.

	* testsuite/ld-powerpc/ppc476-shared.lnk: Align .bss.
	* testsuite/ld-powerpc/ppc476-shared.d: Adjust.
	* testsuite/ld-powerpc/ppc476-shared2.d: Adjust.
