If you don't have ELF shared libraries, you may need to modify collect/init.h.

In a pinch, you might even need to go so far as calling pct_on(argv) from your
main() function.  To be minimally annoying, this still only activates profiling
when PCT is set.

The most useful collector, collect/itimer.c, has definitions in itimer.h for
various CPUs and operating systems.

The script collect/gen-maps probably also needs to be ammended for some new OS
in terms of shared library offsets.
