Yes, if you play games with lma and vma you can easily create layouts that
_bfd_elf_map_sections_to_segments won't handle very well.  A section that has a
different lma to vma relationship to the previous section can't be put in the
same load segment.  That can easily lead to empty load segments, and indeed
must if a section is empty but your script said it should be kept and its lma
to vma relation doesn't match any non-empty section.  (LMA is not specified in
ELF section headers, only in load headers.)

I'm not interested in trying to make every weird user script produce the
minimum number of load headers, or even to work with objcopy.
