* mips-linux-tdep.c (mips_linux_syscall_next_pc): New function.

Browse source 
(mips_linux_init_abi): Set tdep->syscall_next_pc.
	* mips-tdep.c (enum mips_fpu_type, struct gdbarch_tdep): Move to
	mips-tdep.h.
	(mips32_next_pc): Handle the syscall instruction.
	* mips-tdep.h (enum mips_fpu_type, struct gdbarch_tdep): New,
	from mips-tdep.c.  Add syscall_next_pc to gdbarch_tdep.
