Add armv6hl

It has been recently added to RPM. This is functionally equivalent to what
Pidora, the Fedora Remix for Raspberry Pi computer uses apart from that it does
not break all other ARM flavours by forcing them to be armv6hl and switches
the base architecture to armhfp instead of arm which seems more appropriate
for an architecture with vfp extensions.
yum manpage: move 'history info' description to its proper place.
