    xtensa: fix XTENSA_NDIFF handling for PR ld/25861

    Fields marked with XTENSA_NDIFF relocations are not negated, they only
    have sign bits removed. Don't negate their values when relaxation is
    performed. Don't add sign bits when the value is zero. Report overflow
    when the result has negative sign but all significant bits are zero.

            * elf32-xtensa.c (relax_section): Don't negate diff_value for
            XTENSA_NDIFF relocations. Don't add sign bits whe diff_value
            equals 0. Report overflow when the result has negative sign but
            all significant bits are zero.
