Ah right. Having the ALIGN() inside the output section causes the linker
to put some filler in there, which makes it a non-empty section, but this
section isn't assigned to a segment so you get a warning from the linker.
I think the proper way to do this is to not put the ALIGN() before the
output section, nor inside it, but _on_ it, like
.data_nosave : ALIGN(0x1000) { .... }
