Atsushi Nemoto pointed me to http://lkml.org/lkml/2005/9/20/68. This
old patch which seems more complete than mine but made it into the kernel.
I just refreshed the patch and added the bits to ensure namespace.pl
uses the right nm binary also - Keith's original patch only fixed the
objdump use.
From: Keith Owens <[email protected]>
Those scripts are meant to work even when they are invoked by hand,
without OBJDUMP being defined in the environment. This is the correct
fix.
