Tried adding the lines into the busybox .config file, but then trying to make it 
still fails in the mount.c program when it still tries to include the three header 
files that no longer exist on the fedora 28 in the /usr/include/rpc directory.

Ended up just removing the mount and umount options from busybox, and it 
then compiles just fine. Reduces busybox file by about 15K. Unfortunately 
adding the mount, umount and required libraries is about an additional 500K. 

Not a huge issue with my g4l project, since it isn't a space issue, but was 
strange that its worked up to now with the setup. 

Already had a few of the other libraries on build since other programs 
requred them. Have to still run a full test.

Thanks.
