We are declaring the dummy section (used to work around a binutils
bug) as PT_NOTE, but we don't have enough bytes for it to be a valid
note header, and kexec userspace complains:
Warning: Elf Note name is not null terminated
Warning: append= option is not passed. Using the first kernel root partition
Warning: Elf Note name is not null terminated
Instead of using the arbitray value 0xf177 (aka "fill"), declare a
no-name no-description note of type 0.

verified on binutils-2.6.17 that the workaround still works (that
is we get a phdr that does not have all zeros in the paddr field,
and a relocatable kernel booted).
