Architecture: mipsel
Machine: sbmips

>Description:
	Build a mips kernel with _MIPS_BSD_API_LP32_64CLEAN set (as does
	the sbmips port) and observe that gdb doesn't work.

>How-To-Repeat:
	Run a program that produces a core file, and try to use gdb on that
	core file.

	swarm:/tmp 10% gdb /usr/pkg/bin/tcsh tcsh.core
	GNU gdb 5.0nb1

	This GDB was configured as "mipsel--netbsd"...(no debugging symbols found)...
	Core was generated by `tcsh'.
	Program terminated with signal 11, Segmentation fault.
