Create the RTEMS source and installation directories

There should be at least 300 Mbytes of space available on the drive where these directories are located. I used /usr/local/rtems/rtems-4.9.2 as the installation target directory. The location of the RTEMS source is not critical. This document assumes that the root of the RTEMs source tree is /usr/local/rtems/source.

Create the directories where the source will be placed and the results of the build installed:

/usr/local/rtems/source
/usr/local/rtems/source/tools
/usr/local/rtems/rtems-4.9.2
