This patch fixes some compilation issues in libgloss when
building a cross-compiler for mips.  This mostly requires new
function prototypes, similar to the changes recently made
by Jeff Law for other targets.

libgloss/ChangeLog
	* kill.c: Prototype _exit.
	* mips/cfe_mem.c (__libcfe_meminit): Add casts to avoid compilation
	warnings/errors.
	* mips/cma101.c: Prototype __cpu_timer_poll and __cpu_flush.
	* mips/syscalls.c: Prototype get_mem_info.
	(sbrk): Add casts to avoid compilation warnings/errors.
	* mips/test.c: Prototype outbyte and print. Fix return type of main.
	* print.c: Prototype outbyte.  Make ptr argument const char*.
	* putnum.c: Update prototype of print to const char*.

Ok?
