It works fine for me. I use it for kernel, userland, ports and package 
installation. Builds from nfs client side work fine, too. Some points you can 
check:    

1.
On your building machine: Does /usr/obj/usr/src/lib/csu/i386-elf/crt1.o exist? 
If not something went wrong with your "make buildworld".
On the target machine: Are kernel and the userland you try to install in sync? 

2. 
From the FreeBSD Handbook: "All the machines in this build set need to 
mount /usr/obj and /usr/src from the same machine, and at the same point." 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/small-lan.html

Are you sure both directory trees exported and mounted correctly?

ie. my /etc/exports line on the nfs server looks like this:
/usr/obj /usr/src /usr/ports -maproot=0:0 -network 192.168.123.0 -mask 
255.255.255.0

My corresponding /etc/fstab lines on the target host:
192.168.123.10:/usr/ports	/usr/ports 	nfs 	rw,-i,-s,-r=8192,-w=8192 0 0
192.168.123.10:/usr/src 	/usr/src	nfs	rw,-i,-s,-r=8192,-w=8192 0 0
192.168.123.10:/usr/obj		/usr/obj 	nfs	rw,-i,-s,-r=8192,-w=8192 0 0

3.
Does nfs properly work? Some cheap low-end NICs possibly show a high packet 
retransmission rate and packet loss. This also can happen, if your nfs server 
is overloaded. You can check this with 'netstat -i -w 5', tcpdump or any 
other network sniffer. In this case tuning of your nfs mounts could help a 
little (man 8 mount_nfs). Try to play around with readsize and timeouts or 
try to use tcp instead of udp.
