Drop --with-system-libunwind.  OABI was sjlj while EABI uses an ARM EABI
specific unwinder implemented in gcc.  This may or may not matter if you
only want to compile the kernel.

The other options should be ok, though I personally wouldn't pass
--disable-threads, --disable-decimal-float, or --disable-bootstrap.
