This is normal.  Sections which have no contents, like the .bss
section, are not copied into a binary image by objcopy.  This is what
most people prefer, as the contents are just zeroes, so there is
little reason to copy them around, send them over serial lines, etc.
The program typically arranges to clear those parts of memory in the
startup code.

You can use a linker script to force the bss sections in the input
file into an allocated section in the output file.  Or you could try
the gcc option -fno-zero-initialized-in-bss.
