RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite
and mean the target won't support dynamic objects. The latter
probably doesn't matter too much since RX is an embedded target, but
it's easy to stop some of the fudges in order to reduce special cases
for RX in the testsuite. The changes make sense in isolation too.

bfd * elf.c (elf_modify_segment_map): Allow empty LOAD segments if
they contain the program headers.
(_bfd_elf_map_sections_to_segments): If the linker created the
PHDR segment then always attempt to include it in a LOAD segment.

to overlap PHDR segments.

before writing them out. Issue an error if the PHDR segment is
not covered by a LOAD segment, unless the backend allows it.
