If you use a host with "new" binutils (2.15.x), but are building "old"

file uses --as-needed, because 2.15.x supported it, but the ld from 2.14
will fail because it doesn't support it.
This was happening about a year ago, and we eventually fixed it by
upping the book's binutils to 2.15.whatever. But similar issues can
come up again fairly easily (and will, every time binutils adds a new
command line option), and upgrading core system packages (binutils, gcc,
glibc) is not necessarily an "easy fix" if they do. It isn't trivial,
in any case.
Thanks for the case-in-point, Byran. The idea that similar issues can
come up, (and as you showed, we have previous examples of them) and that
the host system can affect the current build method was what I was
trying to express earlier.
