[PATCH] avr32: __div64_const32 is not ok

[Guenter Roeck]

Building avr32 images may fail with errors such as

ERROR: "__avr32_udiv64" [fs/btrfs/btrfs.ko] undefined!
ERROR: "__avr32_udiv64" [drivers/watchdog/kempld_wdt.ko] undefined!

gcc for avr32 generates those symbols for certain constants used
as divisor in do_div(). The problem can be avoided by setting
__div64_const32_is_OK to false for the architecture.
