Hmm. Did you try the binary snapshot on the following URL?
	ftp://ftp.netbsd.org/pub/NetBSD/arch/arc/snapshot/20000303/

Perhaps this might be caused by compiler option of make build.
I've heard that -mips3 option causes this trouble.

No. This seems to be toolchain configuration problem.
Please look at /us/rsrc/gnu/dist/gcc/config/mips/netbsd.h.
Standard gcc already should have this definition.
