>Description:
	The riscv64 port cannot run "systat vm".

	Trying to do so quickly flashes an error message before
	clearing the screen.  Catching it with "script" reveals:

	systat: nlist: can't find following symbols:
	_intrnames
	_eintrnames
	_intrcnt
	_eintrcnt
	_allevents

	Searching for these with "nm -op /netbsd" reveals only

	riscv64: {31} nm -op /netbsd | grep alleve
	/netbsd:ffffffc0008506f8 D allevents
	riscv64: {32} nm -op /netbsd | grep intrna
	riscv64: {33} nm -op /netbsd | grep intrcn
	riscv64: {34} 

	so it is evident that the kernel isn't providing the information
	that systat expects.

	Note that the allevents symbol doesn't have the preceding _ character.

>How-To-Repeat:
	See above.
>Fix:
	Yes, please.
	This is about as essential as "tail -f buildlog" working...
