As an additional data point, gdb uses the extra .romfs segment
correctly too. So it is only some elf parsers that are doing it wrong.

I use gdb with jtag tools on a number of targets (mostly ColdFire
and ARM) and it always loads the .romfs segment along with the
.text/.data where the headers say it too.
