    gcc: drop obsolete header checks

    <limits.h>, <locale.h>, <stdlib.h> are guaranteed by C89. I've left
<string.h>
    for a followup because of a complication that I'll address later.

    gcc/ChangeLog:
            PR bootstrap/112422

            * acinclude.m4 (gcc_AC_C_CHAR_BIT): Don't check HAVE_LIMITS_H.
            * config.in: Regenerate.
            * configure: Regenerate.
            * configure.ac: Don't search for limits.h, locale.h, stdlib.h.
            * intl.h (GCC_INTL_H): Always include locale.h.
            * system.h: Always include limits.h.
            Always include stdlib.h.
