I would like to know how to recompile stap with larger
-DSTP_OVERLOAD_THRESHOLD
and disable the heuristic probe overhead exceeded threshold with
-DSTP_NO_OVERLOAD
FYI, I took these directives from
http://sourceware.org/systemtap/wiki/TipExhaustedResourceErrors
Thank you in advance,

These are not compiler options for building stap, but rather for
building the modules that stap produces. So just pass the values as
command line options to stap at runtime.
The meaning of these variables is described in more detail at the end of
the SAFETY AND SECURITY section of the stap.1 manpage.

You may put permanently-desired stap options into a
$HOME/.systemtap/rc file (stap version 1.7 and later).
