No, they were all using the 3.12 kernel headers:

and all of them were successful, except:
* AVR32 (problem exposed above)
* SH4 (a multilib problem for which I know the cause)

Well, the difference between all of these builds and the AVR32 one is
obviously that AVR32 is using uClibc 0.9.31, right? Seems like uClibc
0.9.33 is not affected by the problem. So I would suggest that a fix is
made to uClibc 0.9.31 to avoid this problem.
Maybe it's just
from our 0.9.33.2 patch stack that needs to be backported to uClibc
