[google/main] Check for cross-compilers in validate_failures.py (issue5674087)

[Doug Kwan]

Hi Diego,

    This patch fixes a problem of the validate_failures.py script that
it rejects cross compilers.  I have tested it by running the script
in the build directory of gcc configure for arm-unknown-linux-gnueabi.
I also tested it on a native compiler for x86.  This should go to both
google/main and trunk.
