Hello!

2014-12-15  Uros Bizjak  <ubizjak@gmail.com>

    * config/i386/gnu-user.h (TARGET_CAN_SPLIT_STACK): Move from here ...
    * config/i386/gnu-user64.h (TARGET_CAN_SPLIT_STACK): ... and here ...
    * config/i386/gnu-user-common.h (TARGET_CAN_SPLIT_STACK): ... to here.

Bootstrapped and regtested on x86_64-linux-gnu {,-m32}, including go.

Will commit tomorrow to mainline if there are no objections.

Uros.
