Description

I have recreated the issue here:
http://review.whamcloud.com/5142

Basically it started when strlcpy was being used in lustre/utils/liblustreapi.c.

For some fun reason we get

...
gcc -g -Wall -fPIC -D_GNU_SOURCE -g -O2 -Werror   -o ll_dirstripe_verify ll_dirstripe_verify.o -L../../lustre/utils -llustreapi ../../libcfs/libcfs/libcfs.a 
../../libcfs/libcfs/libcfs.a(libcfs_a-user-prim.o): In function `cfs_create_thread':
/home/build/lustre-release/libcfs/libcfs/user-prim.c:241: undefined reference to `pthread_create'
...

If you drop the small change out the system builds fine.
