Disable sibling call optimization based on binutils version. This is to work around a bug in the assember in binutils versions < 2.22. Branches to weak symbols can be incorrectly optimized in thumb mode to a short branch (b.n instruction) that won't reach when the symbol gets preempted.

Can previous reviewers ack or test this? I would like to have it in the ARM master branch in time for 12.07.

Hi Albert, just checking on the status of applying this to u-boot-arm. I have a patch series to enable thumb for tegra that needs this. I'll probably just keep a copy of this in that series until it goes in.
thanks, -Allen
