 The real issue is that the compat_netbsd32 code references do_nfssvc 
 from object file netbsd32_nfssvc.o (which in turn resolves other 
 references to netbsd32_nfssvc (a compat syscall entry point).
 
 The compat_netbsd32 module unconditionally includes these references to 
 nfs.
 
 So to remove the dependency, you have to rebuild the module without nfs 
 support.  Removing netbsd32_nfssvc.c from the list of source files, as 
 well as updating source files netbsd32_syscalls.c and netbsd32_sysent.c, 
 would be required.
 
 Making these changes would prevent use of the nfssvc sys-call in 32-bit 
 images.  So, if you have a 64-bit system and only 32-bit userland, you 
 would lose the ability to run the /usr/sbin/nfsd or /usr/sbin/mountd 
 32-bit images.
 
 I suspect we could split the NFS-related stuff into a separate module 
 (compat_netbsd32_nfs) ...
