gcov-tool.c invalid conversion error building gcc 5.2.0 on ia64 HPUX

[Brian Groose]

This looks the same as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66319, except I'm on ia64
instead of pa.  I wasn't quite sure how to apply those same changes to
my local copy of the gcc source code fir ia64, if that's even the
right approach.  Any idea what might be wrong here?
