Make linker-created symbols relocatable where appropriate.
Linker-created symbols like __ehdr_start, __etext, __edata, and end

* output.cc (Output_segment::first_section): Return NULL if there are
no sections in the segment.
* output.h (Output_segment::first_section_load_address): Assert that
first section is not NULL.
* symtab.cc (Symbol_table::sized_write_globals): Attach linker-created
segment-relative symbols to first section of the segment.
