Assume that <sys/ptrace.h> provides a valid ptrace prototype
We used to explicitly list architectures where <sys/ptrace.h> from glibc
is known to provide a valid prototype for ptrace, and use a homegrown
replacement for all the rest. Situation seems to be better nowadays,
glibc is not the only libc available, so let's use ptrace prototype from
<sys/ptrace.h> by default, leaving the replacement for rare broken cases
if any.
* defs.h: Use ptrace prototype workaround iff
NEED_PTRACE_PROTOTYPE_WORKAROUND is defined.
