I suspect ivykis (lib/ivykis/) is a bit buggy when
cross-compiling. Since it fails to detect pthread_spin_lock, it will
have HAVE_PTHREAD_SPIN_LOCK disabled, which in turn means that it will
try to typedef pthread_spinlock_t to an int. But! Your embedded platform
DOES have pthread_spin_lock_t, so this will fail.

I would suggest editing lib/ivykis/config.h after configure, and
enabling HAVE_PTHREAD_SPIN_LOCK.

Hopefully this'll help.

(Why the detection fails, though, is not entirely clear to me..)
