i think the answer is you can't with only released open source projects.

the microblaze gcc config specs refer to a libxil.a that doesn't appear in gcc
or newlib or libgloss, so i assume it's a bsp thing you get from xilinx.

ignoring that, the microblaze sim doesn't have syscall support hooked up.  so
it's only a CPU simulator atm.
