If you want to see the actual sizes of things you can either use the "size"
program or the objdump program:

$ size elfFileName
$ objdump --sectionHeaders elfFileName

depending on how the tools were build, you may have to put a prefix on the
program names:

$ arm-elf-size elfFileName
$ arm-elf-objdump --sectionHeaders elfFileName

Objdump and objcopy are extremely useful programs.  They can do lots of
different handy things. Read the man pages for both of them.  Honestly, it's
worthwhile.
