I've become a little rusty on the x86 target code but it looks OK to
me. The simple approach that HJ has taken is quite suited to a
release branch, as compared to redesigning x86_64 ifunc support..
(The latter might be preferable on mainline to avoid the reloc
scanning, if possible, but I leave that decision to HJ.)
