Added --enable-ptrace

Browse source 
This change adds a manual override to control building of the ptrace
library, similar to the existing --enable-coredump option.  The
default is set based on the existence of sys/ptrace.h, allowing it
to be automatically disabled for platforms that do not have ptrace.
