Build performance tuning for OE/Yocto

* Recommended free disk space: about 100 Gbytes
* Put the build directory on its own disk. This is good practice in its own right since the build system has a tendency to wear disks heavily.
* Use the ext4 filesystem for the build disk
* Turn off journaling for ext4 (“$ tune2fs -O ^has_journal <disk>")
* Mount using the options "noatime,barrier=0,commit=6000"
* Use a tmpfs for /tmp

Example of '''/etc/fstab'''

# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
UUID=/dev/sda1 / ext4 noatime,barrier=0,commit=6000,errors=remount-ro 0 1
UUID=/dev/sda5 none swap sw 0 0
/dev/ram0 /tmp tmpfs size=1G 0 0
