Thanks for mentioning that. I assumed that since binutils "ld -z
ignore" worked, that it paid attention to the "-z ignore" option. It
doesn't; it ignores it (:-). I just now verified this by inspecting
the source code; there is undocumented support for emulating
Solaris-style ld -z directives, but -z ignore is merely ignored.
The original lib-ignore.m4 didn't have this problem because it used
'ldd' to verify that -z ignore actually ignored. However, 'ldd' was
not portable enough, so I removed 'ldd' (see
<http://lists.gnu.org/archive/html/bug-coreutils/2006-01/msg00132.html>)
and that is what introduced the problem.
I installed this patch into coreutils.

* m4/lib-ignore.m4 (gl_IGNORE_UNUSED_LIBRARIES): Prefer binutils's
--as-needed option if available. Problem reported by Albert Chin in
<http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00114.html>.
