No. I used my old script.

Thanks. It works for me now. "make cross" did confuse me.

Here is a libgcc2 patch for cross compile. When I do cross compile for
Linux, I need a libgcc.a which is identical to the native compiled
libgcc.a. The current libgcc2.c doesn't support it. I used the patch
below to get around it. I added -Dno_inhibit_libc to my CFLAGS so that
my cross compiled libgcc.a is the same as the native compiled libgcc.a.
