While compiling NetBSD-current for sparc64 I noticed the following error:

In file included from /opt/src/sys/arch/sparc/stand/ofwboot/net.c:61:

nbmkdep: compile failed.

I was building 'release' via build.sh, however the above error did not cause
the build to fail, i.e. the error seems to have been ignored.

So the question: is this a harmless error which can be ignored?
