Glad it worked for you. :)

Alas, he hit hard limits.  I should retry this on current 2.6 and see if
the elf interpreter these days works the same way.

Also, last year I was poking at the kernel's elf interpreter and the
uClibc dynamic linker:

I should really go back and write some proper documentation for all
that, but as with so many things my todo list sort of composts as new
layers get thrown on top of the previous priorities faster than I
actually do them.  Some stuff bubbles back up to the surface and others
sink for years at a time...

(Currently the x86_64 target isn't working with uClibc-1.0-rc3 because
it claims some code it's trying to suck into libc.so.0 didn't get built
with -fpic.  Yet more todo items to track down...)
