Dynamic loader usage in RTEMS 5.1

[Gedare Bloom]

Hi John,

Have you studied the libdl tests yet? Code is in
rtems.git/testsuites/libtests/dl* and build rules are in
rtems.git/spec/build/testsuites/libtests/dl*

You can probably get some hints from looking at the build log and the
command that gets created.
