Could you please send more info?
uname -m
uname -a
gcc --version
gcc -dM -E -x c  /dev/null

and the generated config.mak (after make cfg).

The problem are the atomic_get_and_set_* instructions which use swp
 (not supported on ARMv7+). However they are easy to replace with 
 a ldrex/strex (one need only to replace the ATOMIC_XCHG_DECL macro
 in atomic_arm with a modified version of the ATOMIC_CMPXCHG_DECL
 macro).
To enable proper SMP support we need also to define some memory
barriers.

However since I don't have access to an ARMv7+, I need the above info
from your machine so that I can modify the Maekfiles to properly detect
a ARMv7.

Thanks,
Andrei
