Regression tests run script will return non-zero value if tests fail.

    * run-tests.sh: return non-zero value if ether elf32 or uclibc tests
    failed.
Use "tr -d" instead of dos2unix, as required option -f is not supported in older dos2unix.

    * arc-init.sh (save_res): Use "tr -d" instead of dos2unix, because
    Synopsys RedHat machines have an ancient dos2unix that doesn't support
    -f option.
