The revision 2.48 change (grossman 1995/10/16) had unfortunately

broken the prompt spotting for the <RISQ> variant of the IDT
monitor. Also took this opportunity to add the vr4300 configure.in
options.

+	* configure.in (configdirs): Added support for the VR4300 default
+ 	builds (mips64*vr4300*el-*-elf*, mips64*vr4300*-*-elf*).
+
+	* configure: Regenerated.
+
+	* remote-mips.c (mips_load): Updated the prompt spotting code to
+ 	make use of the TARGET_MONITOR_PROMPT manifest.
