These are arguments that are not yet supported by gcc.  My understanding
is that they are (or were planned to be) in the Cygnus/RedHat source but
apparently still have not been merged.  You can search the newlib archives
but I have included the post here (watch tabs when applying the patch,
I just cut and pasted):

Joel,

  I got sloppy.  It should have been removed as well.  The attached patch
should be applied on top
of the previous one.  Again, this only applies to users that configure
for the v850.

You need to build the C library and install it before crt0.o is there.
