But that won't do anything, because the nonmove sbrk flag is zero. 
I think you need to turn off the Unixy sbrk, then turn on non-move
sbrk; this will work whichever of the flags is zero or nonzero:

    _crt0_startup_flags &= ~_CRT0_FLAG_UNIX_SBRK;
    _crt0_startup_flags |= _CRT0_FLAG_NONMOVE_SBRK;
