[iproute2] enable transparent LFS

From: Mike Frysinger <vapier@chromium.org>

Make sure we use 64-bit filesystem functions everywhere.  This applies not
only to being able to read large files (which generally doesn't apply to
us), but also being able to simply stat them (as they might be using large
inodes).

I am okay with this, is something specific it fixes or is it just
general good practice?

general good practice at this point.  we've started Gentoo down the path of 
killing off non-LFS in projects.
