* elf-nacl.c (nacl_modify_segment_map): Fix logic reordering the
elf_segment_map list. If an executable segment is page-aligned
but does not end with a full page, then append a fake section into
the segment map entry that pads out the page.
(nacl_final_write_processing): New function. Write the code fill
laid out in nacl_modify_segment_map.
* elf-nacl.h: Declare it.
* elf32-arm.c (elf32_arm_nacl_final_write_processing): New function.
(elf_backend_final_write_processing): Define it for NaCl backend.
* elf32-i386.c (elf_backend_final_write_processing): Likewise.
* elf64-x86-64.c (elf_backend_final_write_processing): Likewise.
* elf-nacl.c (segment_eligible_for_headers): Rename MAXPAGESIZE
parameter to MINPAGESIZE.
(nacl_modify_segment_map): Use minpagesize instead of maxpagesize.
* elf32-arm.c (ELF_MINPAGESIZE, ELF_COMMONPAGESIZE): Set to
0x10000 for NaCl targets.
ld/testsuite/
* ld-x86-64/ilp32-4-nacl.d: Loosen .shstrtab line regexp to match
any file offset.
* ld-x86-64/tlsbin-nacl.rd: Update expected code segment PT_LOAD.
* ld-x86-64/tlsbindesc-nacl.rd: Likewise.
* ld-scripts/rgn-at3.d: XFAIL for *-*-nacl* targets.
* ld-scripts/rgn-over8-ok.d: Likewise.
