A patch to address this problem has been available for some time [1].

Also:

Building score:defconfig ... failed
--------------

FATAL: The relocation at __ex_table+0x91c references
section "__ex_table" which is not executable, IOW
the kernel will fault if it ever tries to
jump to it. Something is seriously wrong
and should be fixed.

A pull request to address this problem was sent to Linus last week [2].
