objcopy can do this, with the --add-section= directive. Note that bzImage is *NOT* an ELF object!
As far as converting a binary file to a .o that can be included in code, GNU ld will do it quite cleanly with:
ld -r -b binary file.bin -o file.o
It creates the symbols _binary_file_bin_{end,size,start} to reference it.
The only problem is that it puts it in the .data segment, and at least I can't find a way to put it in the .rodata segment instead. I've been thinking about submitting a patch to bfd that would define a "robinary" format (same as binary except it is all .rodata).

True enough.
