 I use the latest rtems-tools to generate RAP file, I found the object file
 become too small(elf,2184bytes==>rap,736bytes) and the file loaded failed,
 error message like this "load app.out error:offset past end of file:
 offset=736 size=736 error."

 I reverted the rtl-rap.cpp commit(
 0ad4aaafc20afcb5aacb7a82b0b3a8150b638975 linker/rap: Ignore relocation
 records with no section), the rap file can be loaded.

 At Chris's suggestion, I founded get_relocations(s) return all the count
 of relocation and write to rap file, but actual count is less, because
 ignore the reloc with section=0.
 I tried to make the length fit the relocs write to rap file, the file can
 not be loaded, it crashed. So the relocs(reloc.symsect == 0) can not be
 ignored, at least on arm.

 The command line I used to create RAP file is like this:
 rtems-ld -n -e appmain -s -O rap --base rtems.elf app.elf -o app.out
