My patch to solve same problems attached

The added complexity of my version comes from preventing leaking out
of the "chroot" through symlinks or "../.." elements. If we have

$HOME/buildroot/usr/lib/libfoo.so.1 -> /usr/lib/libfoo.so.1.2 ->
/usr/lib/libfoo.so.1.2.3

and if the buildroot and host system have different versions of the
library, realpath can't be used. It gets a little messy, I agree. I
had to do similar logic in scratchbox2 to maintain the fake chroot.

regards, Lauri
