Make script rtems-bsps compatible with GNU find

[Pavel Pisa]

Hello Chris and others,

the depth argument changes order of find output only
according to GNU find manual

   -depth Process  each  directory's  contents before the directory
    itself.  The -delete action also implies -depth.


The following value 5 is then considered as path argument
but for GNU find such argument are illegal after the first
filter option. maxdepth is the right argument for GNU find
for intended limitation

   -maxdepth levels
    Descend at most levels (a non-negative integer) levels of directories
    below the command line arguments.  -maxdepth 0
    means only apply the tests and actions to the command line arguments.

If the -maxdepth is accepted by your/others BSD, OS X, Cygwin
finds flavors then next change would make script to run on Linux.

Best wishes,

              Pavel
