[coreutils] [PATCH] Cater for extra strace output when building 32-on-64.

[Nix]

When building 32-bit coreutils on a 64-bit Linux platform, the
stat-free-symlinks test fails because the strace output it diffs
against contains an extra informative line emitted by strace
of the general form

[ Process PID=28429 runs in 32 bit mode. ]

So dike that line out, if it exists, before running the comparison.
