Status in “apr” package in Ubuntu: New

Bug description:
On armv7/thumb on Maverick, apr fails to build because it deadlocks in testing shared (interprocess) mutex locking. This feature likely depends on atomics behavior in glibc pthread spinlocks that is broken in thumb2.  I have a simple patch that disables shared process mutexes for arm just like was needed for sh4.
