There are two other options.
* save/restore floating registers in rtld. A performance impact of this
is likely minimal given how big is overhead. As it would need
consensus this is unlikely for 2.18
* I recalled that I removed memset-x86-64 as unused. Now I am bit
puzzled why it was not used by rtld.
So we could dig sysdeps/x86-64/multiarch/memset-x86-64.S rename it to
rtld-memset.S and adjust names.
