No, this sort of thing is exactly why we have obj symlinks and
/usr/obj.  On your NFS server, export /usr/src.  On each client, make
/usr/obj be a local directory and NFS mount /usr/src from the server.
Now all you need to do is run 'make obj' from /usr/src on each client,
and it will build a directory hierarchy under the local /usr/obj for
the binaries it needs.

See make(1) and /usr/share/mk/bsd.{README,obj.mk}.
