But your patch effectively changes --relax-branch to mean
"warn about branch relaxations that are otherwise applied
by default if -mno-embedded-pic".  At the same time it's
still acting as "enable branch relaxation" when used with
-membedded-pic.  Seems a bit convoluted.

At the end of the day, it is only a warning.  If you really
want a way of turning it off, why not put it under the control
of a separate flag?
