hangs/crashs on ARM/AARCHXX

[vanhauser-thc]

Hi,

I just noticed that drcfg hangs when run on ARMv7/AARCHXX:

drrun -c drcfg.so -only_from_app -no_cti -- /bin/true

and it crashes when using -no_cbr :

# drrun -c drcfg.so -only_from_app -no_cbr -- /bin/true
<Application /bin/true (10919).  Dynamic CFG-generator internal crash at PC 0x71099d98.  Please report this at toshi.piazza@gmail.com.  Program aborted.
