* layout.cc (Layout::set_segment_offsets): Align the file offset
to the segment aligment for -N or -n with no load segment.
* output.cc (Output_segment::add_output_section): Don't crash if
the first section is a TLS section.
(Output_segment::set_section_list_addresses): Print an error
message if the address moves backward in a linker script.
* script-sections.cc
(Output_section_element_input::set_section_addresses): Don't
increase *dot_value for a SHF_TLS/SHT_NOBITS section.
(Orphan_output_section::set_section_addresses): Likewise.
