I mistakenly based this patch on version 2010.11.

Actually, since I use an external toolchain, the patch of Matias Garcia 
(http://lists.busybox.net/pipermail/buildroot/2011-July/043944.html, not 
merged yet) solves the -te500v2 problem for me without this patch, so I've 
dropped it locally.

Ah, something new learnt. Thanks for noticing and fixing, and thanks again for 
your great work.

(Back to my cross Poco C++ build attempts)
