  Log:
  Fixed -mprofiler-epilogue.  The garbage collector apparently doesn't
  understand that non-local variables can never be collected, and when
  it collected the static variable for mexitcount_libfunc, gcc aborted
  on the next use of this variable.
  
  This quick fix is to reinitialize the variable on every use and depend
  on garbage collection recovering the small amount of memory wasted by
  this, and not worry by the small amount of time wasted by this.  It
  would be better to initialize the variable together with most of the
  other libfuncs in optabs.c and depend on whatever magic is there to
  prevent its collection, but we initialize it here to avoid taking at
  least 2 more files off the vendor branch.
