rtems dynamic library loading

[Peng Fan]

Hi,

would you please have a try using rap format? does your elf  file symbol
table contain the "puts" symbol?
If using rap format, you can use rtems-syms to check it. I am not sure
whether your command is right since i did not work on  this for a long
time, I just downloaded the source code yesterday, and rebegin do
something:)
