I can get NFS to work with just portmap running, but it throws an odd, yet
non-fatal, error when mounting the remote share (don't have the actual error
text available at the moment).  I was hoping that having rpcbind running as
well as portmap would eliminate that.  However, current rpcbind needs
libtirpc to build, and that fails on uclibc-ng because of a missing header
file "rpcsvc/yp_prot.h".

Buildroot posted a patch to fix this in libtirpc itself, just haven't had
some free time to test it yet:
http://lists.busybox.net/pipermail/buildroot/2015-July/133890.html

Can't use the internal (minimal?) RPC mechanism, either.  I had to enable
the full RPC stack in order for portmap to actually build.
