See the same for INIT in /bin/sh.  However, the INIT value of interest
here is that for /lib/libc.so.6:

dave at mx3210:~/gnu/gcc-4.3/objdir/hppa-linux/libjava$ readelf -a /lib/libc.so.6|grep INIT
 0x0000000c (INIT)                       0x1f164

This was the value at r21 + 4.  This value also isn't an OPD.  However,
I showed before that init() didn't get called using an OPD.  As a result,
r19 was likely incorrect for the call.  See the code snippet in the
original report.

Possibly, there's a GCC optimization bug but I'm not sure.
