    Ignore degenerate PT_LOAD segments
    
    Fixes a failure triggered by -z separate-code.  p_memsz is tested
    rather than p_filesz for objcopy --only-keep-debug where p_filesz is
    set to zero.
    
    	PR 22845
    	* elf.c (assign_file_positions_for_non_load_sections): Ignore
    	degenerate zero size PT_LOAD segments when finding one overlapping
    	the PT_GNU_RELRO segment.

    ld-elf/eh4: Pass -z max-page-size=0x200000 -z noseparate-code to ld
    
    -z separate-code creates separate code LOAD segment, aligns it to the
    maximum page size and places .plt section before .text section.  But
    ld-elf/eh4 passes -Ttext 0x400 to linker to place .text section at
    address 0x400, which is impossible for linker to accomplish:
    
    $ ld -shared -Ttext 0x400 -z separate-code -o x.so eh4.o
    ld: section .eh_frame LMA [0000000000200000,000000000020006b] overlaps section .plt LMA [0000000000200000,000000000020001f]
    
    Since ld-elf/eh4 also checks exact addresses, this patch passes
    -z max-page-size=0x200000 -z noseparate-code to ld.
    
    	PR ld/22845
    	* ld-elf/eh4.d: Pass -z max-page-size=0x200000 -z noseparate-code
    	to ld.

    ld-elf/ehdr_start: Pass --build-id to ld
    
    ld-elf/ehdr_start fails with -z separate-code.  Since there is no data
    LOAD segment before code LOAD segment:
    
    There are 2 program headers, starting at offset 64
    
    Program Headers:
      Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
      LOAD           0x200000 0x0000000000600000 0x0000000000600000 0x000010 0x000010 R E 0x200000

     Section to Segment mapping:
      Segment Sections...
       00     .text

    the program header isn't included in any LOAD segment.  As the result,
    reference to __ehdr_start is resolved to zero.  Pass --build-id to ld
    to add a data LOAD segment before code LOAD segment to put the program
    header in the  data LOAD segment.
    
    	PR ld/22845
    	* testsuite/ld-elf/ehdr_start.d: Pass --build-id to ld.

    PT_LOAD and PT_GNU_RELRO segment overlap
    
    Commit 325ba6fb34 excluded degenerate zero length PT_LOAD segments,
    but that only fixed part of the problem, which was that the load
    segment limits were not calculated properly.
    
    	PR 22845
    	* elf.c (IS_TBSS): Define.
    	(_bfd_elf_map_sections_to_segments): Use IS_TBSS.
    	(assign_file_positions_for_non_load_sections): Revert last change.
    	Properly calculate load segment limits to compare against relro limits.
