    build: Use -nostdinc generating macro_list [PR109522]

    This prevents a spurious message building a cross-compiler when target
    libc is not installed yet:

        cc1: error: no include path in which to search for stdc-predef.h

    As stdc-predef.h was added to define __STDC_* macros by libc, it's
    unlikely the header will ever contain some bad definitions w/o "__"
    prefix so it should be safe.

    gcc/ChangeLog:

            PR other/109522
            * Makefile.in (s-macro_list): Pass -nostdinc to
            $(GCC_FOR_TARGET).=
