nfs-utils configure searches for rpcgen tool only in default locations:
"/usr/local/bin/rpcgen /usr/bin/rpcgen /bin/rpcgen".
On some of our build machines the rpcgen is not present there and
configure fails:
| configure: error: Please install rpcgen or use --with-rpcgen
HOSTTOOLS_DIR already contains a correct pointer to host rpcgen tool, so
use it from there.
