CVS build fails for x86 (SUSE 9.3, gcc 4.2.1) with multiple definition of __memcpy_chk

Hi!

Just wanted to let you know, that for me the build of a current CVS
snapshot of libc fails for x86 while it works for x86_64.

Error messages are:

As far as I can see, the problem is that definitions of __memcpy_chk are
drawn in from string/memcpy.os as well as from debug/memcpy_chk.os
(probably originating from sysdeps/i386/i586/mempcpy.S as well as from
debug/memcpy_chk.c).

Configure line was:
../libc/configure --prefix=/usr --enable-add-ons=nptl --host=i586-linux-gnu

> gcc -v
Using built-in specs.
Target: i586-suse-linux

--program-suffix=-4.2 --enable-version-specific-runtime-libs
--without-system-libunwind --with-cpu=generic --host=i586-suse-linux
Thread model: posix
gcc version 4.2.1 (SUSE Linux)

The problem is not critical for me as I only need the x86_64 build;
however if you are interested in debugging the issue, I'm happy to help
as far as I can. :-)
