Learned a few things in this process. I appreciate all the help and advice.

 1. So we know that at least with Edison, btrfs does not work with bitbake.
 2. When I rebuilt the system, this time I put the Linux root directory
    on an 80GB SSD.  That is where I also have my clone of Linux-Yocto
    repository, poky, and download directory , DL_DIR.
 3. I have create /build with EXT4 format on a Software RAID 0 (striped)
    partition, using 2 separate hard drives,  to use as the working
    build directory for bitbake. I have a striped swap file on the same
    two drives.  But with 8GB or RAM, I shouldn't be using that much.

My build times for some of the basic meta-intel BSPs is around 103 minutes.
