The problem is now clear to me.  The fix that I sent seems to work ok
under hpux.  Binutils now has no failures and I did a complete bootstrap
of gcc with it.

The patch that I sent causes all recursive calls to have relocation data.  
This may not be optimal as recursive calls shouldn't need relocation
data.  However, the testing needed to determine if a call is recursive are
more complicated than what I submitted.  As far as I could tell, branches
within procedures still have no relocation data.  It is only branches
to procedure entry points that present a problem.

If you want to eliminate the relocation data for recursive calls, then
for example, the weak/external check must include a check to see if
this is not a recursive call to the symbol.  Further, in the old code,
long branches always have relocation data.  This would also have to be
fixed.
