Yep, sounds like a reasonable idea, though these calls to
"strncat(buf, str, strlen(str))" in the iscsi driver are still a
little insane.  Could you suggest a patch to arch/m68k/Makefile to do

    [PATCH] x86_64: Don't define string functions to builtin

    gcc should handle this anyways, and it causes problems when
    sprintf is turned into strcpy by gcc behind our backs and
    the C fallback version of strcpy is actually defining __builtin_strcpy

    Then drop -ffreestanding from the main Makefile because it isn't
    needed anymore and implies -fno-builtin, which is wrong now.
    (it was only added for x86-64, so dropping it should be safe)
