It looks like I may have been mistaking your problem with a known bug in
some versions of binutils.

What does "arm-elf-objdump -h" on the *ELF* version of the file (i.e.
myfile.out) say? In particular, look at the LMA - that should indicate some
section with an address about 16Mb away from the rest.
