I think it is related to:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=63a478fbc05cb0627b0a33a69f3aed8dcb965953
and the fact that the armel/marvell flavour has CONFIG_VFP set now
which breaks the heuristic used there.
armel/kirkwood had it disabled, but armel/orion5x had it enabled, so
the merge of the two took the superset (which was the right thing to
do). armel/orion5x had always had it enabled AFAICT.

You can set KBUILD_DEBARCH=armel on the make deb-pkg command line to
override it.
