2010-12-22added libnxt as a dependent libraryTC Wan
Added libnxt as a dependent library instead of using system provided package. This is mainly due to the difficulty in getting libnxt installed using MacPorts.

2010-12-16fix undef handler instruction address calculation, arm7 does not recognize ↵TC Wan
bkpt instruction coding The Undef handler was adding to instead of subtracting from PC to get the BKPT instruction address. ARM7 does not recognize BKPT instruction coding. Modified instruction code to use UNDEF instruction prefix instead. Refer Steve Furber, ARM SOC Architecture, 2nd Ed, pg 143
2010-12-15added stub routines for debug_procsetregs and debug_procsetoneregTC Wan
