Re: Fix moxie libgloss issues with c99

Two libgloss issues specific to moxie-elf that show up build with GCC trunk.

First, putnum.c uses "print" without a prototype.  So I added one based on the
function's definition in print.c.  Second sim-inbyte.c uses read, which comes
from unistd.h, so this adds a suitable #include.
