coreutils-8.4: strace induced test failure

[Bruno Haible]

Hi,

Trying to install coreutils 8.4 on a x86_64 Linux/glibc system, I get a test 
failure.
Relevant parts of test-suite.log:

=============================================
   GNU coreutils 8.4: tests/test-suite.log   
=============================================

1 of 370 tests failed.  (46 tests were not run).

I had configured coreutils like this (native 32-bit mode build on a 64-bit
system):
$ ./configure --host=i686-pc-linux-gnu --prefix=/arch/x86-linux/gnu \
  CC="gcc -m32 -march=i586" CXX="g++ -m32 -march=i586" LDFLAGS="-m32" \
  CPPFLAGS=-Wall

$ which strace
/usr/bin/strace

The function in require_strace_ in tests/test-lib.sh does
  strace -qe stat echo
and tests the return value.

$ strace -qe stat src/echo
[ Process PID=31238 runs in 32 bit mode. ]

$ echo $?
0

But this 'strace' program does not fully work on 32-bit mode executables:
1) It always emits this "Process PID=xxxxx runs in 32 bit mode." message.
2) It does not support some system calls: 'write' and 'fstat64' appear 
supported,
   but 'stat' is not:

   $ strace -qe stat src/ls
   [ Process PID=31310 runs in 32 bit mode. ]
