    Don't convert R_X86_64_GOTPCREL if it will overflow

    When converting "mov address@hidden(%rip), %reg" to "lea foo(%rip), %reg"
    with R_X86_64_PC32 relocation, it may overflow if the target section
    is more than 2GB away.  This patch estimates distance between mov
    instruction and the target section.  We convert R_X86_64_GOTPCREL to
    R_X86_64_PC32 only if their distance is less than 2GB.

      PR ld/18591
      * elf64-x86-64.c (elf_x86_64_convert_mov_to_lea): Don't convert
      R_X86_64_GOTPCREL to R_X86_64_PC32 if it will cause relocation
      overflow.
