I'm not the author of --sysroot changes, but I'd say that it is again user
error:

> sudo /usr/powerpc-g2.20-linux-gnu/sbin/ldconfig -v  -C
> /usr/powerpc-g2.20-linux-gnu/etc/ld.so.cache -f
> /usr/powerpc-g2.20-linux-gnu/etc/ld.so.conf

If you have sysrooted file, you should use .../ldconfig -r
/usr/powerpc-g2.20-linux-gnu/ ...
(of course only if you actually can run the binaries, in most cases you are
cross-compiling for incompatible architecture and you need either emulator, or
can't run it at all).
Anyway, I don't think gcc bugzilla is the right forum to learn about sysroots.
