[PATCH] fix static linking of NFS

Builds on ARM report link problems with common configurations like
statically linked NFS (for nfsroot).  The symptom is that __init
section code references __exit section code; that won't work since
the exit sections are discarded (since they can never be called).

The best fix for these particular cases would be an "__init_or_exit"
section annotation.
