Comment 5 for bug 1676834

This seems to work. But I think the modifications of stress-ng.h are buggy - defining ALIGN64 or not should _not_ depend on HAVE_ALIGNED_64K - it should still just depend on the compiler being non-ancient (and implicitly assume that the rest of the toolchain, assembler and linker, always supports 64 bytes alignment - which isn't necessarily true, nor is a cache line always 64 bytes, but in practice this should be good enough, at least until someone actually files a bug report).
