Fix a long standing bug.  NextObject is the first field for very long time.
Implement guest vcpu pinning using 'pthread_setaffinity_np(3)'.

Prior to this change pinning was implemented via an ioctl (VM_SET_PINNING)
that called 'sched_bind()' on behalf of the user thread.

The ULE implementation of 'sched_bind()' bumps up 'td_pinned' which in turn
runs afoul of the assertion '(td_pinned == 0)' in userret().

Using the cpuset affinity to implement pinning of the vcpu threads works with
both 4BSD and ULE schedulers and has the happy side-effect of getting rid
of a bunch of code in vmm.ko.

Allow us to build clang for ARM EABI. Clang and llvm use the
arm-gnueabi-freebsd10.0 triple for EABI. Use this when we are on arm or
armv6 and are building for EABI.

When clang builds libc it may insert calls to __aeabi_* functions. Normally
this is not a problem as they are resolved by libgcc. The exception is for
the __aeabi_mem* functions. These call back into libc to the appropriate
function. This causes issues for static binaries as we only link against
libc once so there is no way for it to call into libgcc and back.

The fix for this is to include these symbols in libc but keep them hidden
so binaries use the libgcc version.
Remove debug output
Substitute '#ifdef ALIGNED_POINTER' with '#ifndef __NO_STRICT_ALIGNMENT',
since the former is defined everywhere. This cuts off some code not
necessary on non strict aligment arches.
