The -fsection-anchors option appears to be important.  If I use
-fsection-anchors (which is default for powerpc64-linux), LTO does not align
the .rodata section, but uses Altivec memory instructions.  If I use
-fno-section-anchors, the .rodata section is not aligned, but it doesn't use
Altivec memory instructions, so the test passes.
