http://cvs.openpkg.org/chngview?cn=16830 reads:
Accept (and ignore) --as-needed/--no-as-needed options from GNU binutils
2.15 in our GNU binutils 2.14 to resolve a chicken and egg problem under
platforms (like Fedora Core 2) which already run GNU binutils 2.15: the
vendor cc(1) knows that it has ld(1) from GNU binutils 2.15 and hence
always uses the --as-needed option when calling ld(1). Unfortunately,
between having built "binutils" and "gcc" packages, this will break
OpenPKG because the vendor cc(1) would run the OpenPKG ld(1) with an
option it (still) does not understand. The only workaround is to let our
ld(1) accept and ignore this option. Once our cc(1) from "gcc" package
is installed, the problem is gone, because our "gcc" package correctly
detects that our ld(1) still does ot understand --as-needed.
