Setting aside those issues already raised by the other response, let me
comment on this line:

1) No debug flags (-g)?  While not strictly needed for profiling, having 
   them in place should be your default.  Who knows --- it might even solve
   your problem.

2) That -imacros override smells fishy.   It's impossible to tell what 
   it actually does without seeing that file, boot.def.  This being in
   your control, *you* have to make sure it doesn't interfere with the
   profiling machinery.

In case of doubt, those libraries may be the cause of your problem,
too.  E.g. if they weren't built with -pg themselves, or they fiddle
with the timers on their own.
