	Since the IRIX 4 configuration was forcing K&R mode it hasn't been
	buildable since GDB 5.0.
	* NEWS: Mention that IRIX 3 and IRIX 4 support were removed.
	* configure.host: Delete "mips-sgi-irix3*" and "mips-sgi-irix4*".
	* configure.tgt: Delete "mips*-sgi-*" a.k.a. irix3.
	* irix4-nat.c: Delete file.
	* config/mips/irix4.mh: Delete file.
	* config/mips/irix3.mh: Delete file.
	* config/mips/irix3.mt: Delete file.
	* config/mips/tm-irix3.h: Delete file.
	* config/mips/nm-irix3.h: Delete file.
	* config/mips/xm-irix3.h: Delete file.
	* config/mips/nm-irix4.h: Delete file.
	* config/mips/xm-irix4.h: Delete file.
	* config/mips/tm-irix5.h: Inline contents of "tm-irix3.h".
