Since 4.6~rc3-1~exp1 built successfully, I'm wondering if maybe something
changed in the generic debian configs (or in the upstream kernel source)
which could have led to this breakage?

Yes, but I tend to think that you are probably right to simply turn
CONFIG_MLONGCALLS back on again.
I do have kernel patches queued for kernel 4.7 which enable FTRACE support,
and those will require CONFIG_MLONGCALLS most likely anyway then.
Furthermore I just checked and I'm building my own test kernels usually with
CONFIG_MLONGCALLS too, so in the long run we will probably not be able
without this option.
Can you turn CONFIG_MLONGCALLS back on for the next upload?
