BTW, I got this build error:

I worked around this by removing some of EFI config options but presumably
this needs to be properly fixed.
Interesting. This build error could be something new. Could you please
post your kernel config?

Attached.

This, BTW, is on a relatively old toolstack:
gcc version 4.8.2 20131014 (prerelease) (crosstool-NG
linaro-1.13.1-4.8-2013.10 - Linaro GCC 2013.10)

Interesting. I cannot repro the error with Linaro GCC 4.9-2014.

This does look like something toolstack-specific: I installed
     gcc version 4.8.3 20140401 (prerelease) (crosstool-NG 
linaro-1.13.1-4.8-2014.04 - Linaro GCC 4.8-2014.04)
from the link you provided above and it built without problems.
