OK, this is just messed up.  If we need jiffies in a special section
then we should declare it as such (see __jiffy_data), but it's not clear
to me why we would.  This seems like hack upon hack.

However, I suspect we may want to put jiffies into a .S file, and that
.S file needs to take into account architectures which need underscore
prefixes (which really sucks to have in ELF and is a major fail on those
ABI designers...)
