Besides the t-cris and t-mmix definitions, -Dinhibit_libc is
also due to this chunk in gcc/configure.in:
---------------
# If this is a cross-compiler that does not
# have its own set of headers then define
# inhibit_libc

# If this is using newlib, then define inhibit_libc in
LIBGCC2_CFLAGS.
# This prevents libgcc2 from containing any code which requires libc
# support.
inhibit_libc=
if [test x$host != x$target] && [test x$with_headers = x]; then
       inhibit_libc=-Dinhibit_libc
else
       if [test x$with_newlib = xyes]; then
               inhibit_libc=-Dinhibit_libc
       fi
fi
AC_SUBST(inhibit_libc)
---------------
so leaving things as they are now seems good enough.  Or maybe
tweak bprob.exp in the added comment to say "__bb_init_func from
libgcc is by default inhibited for newlib and cross targets".
