Compile instructions for version 2.1 of the JNOS installer

1) Take the sole source file, jnosinstaller.c, put it in some directory, then
   enter the command, 'make jnosinstaller'. That will create a binary of the
   same name. Don't worry about warnings, as long as it creates the binary.

2) Take any of the JNOS installer packages from the official website, follow
   instructions to extract the files, up to the point of 'cd installerv2.1'.

   Now, instead of running './jnosinstaller', you need to FIRST copy a couple
   of files into this 'installerv2.1' directory. One of the files will be the
   new installer that you just compiled above in step 1). If you are compiling
   your own installer, chances are you will also have to compile your own JNOS
   binary. This will be the second file to copy into this 'installerv2.1'
   directory.

   AFTER you have copied the two files above, THEN run './jnosinstaller'.

3) That's it, if all goes well, you should have a new 'jnos' install.
