arm: work around assembler bug 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. http://sourceware.org/bugzilla/show_bug.cgi?id=12532 Signed-off-by: Allen Martin <amartin@nvidia.com> Acked-by: Tom Rini <trini@ti.com>
