code review for FDS and dtrace work around (7165060)

[Daniel D. Daugherty]

Greetings,

This is a code review request for a work around for a Full Debug Symbols
and DTrace work around on Solaris. The gobjcopy utility on Solaris 10
corrupts the SUNW_dof section of libjvm.so. I've created a minimal tool
that adds the ".gnu_debuglink" section to libjvm.so without corrupting
other sections in the libjvm.so file.

Here is the webrev URL for the HSX-24 version:

This fix has been reviewed internally by Serguei Spitsyn (sspitsyn),
Karen Kinnear (acorn) and some folks from different Solaris groups.

This fix will also be backported to HSX23.2/7u6 and I expect the
changes to virtually identical.

Thanks, in advance, for any additional reviews!

Dan
