            Bug ID: 31252
           Summary: relocations to local symbols not handled with -r
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux

Given an input with


    leaq    .Lstr(%rip), %rdi

    .section    .rodata.str1.1,"aMS", at progbits,1
    .asciz "abc\n"

lld -r will produce

000000000003  000000000002 R_X86_64_PC32                        -4

while bfd produces

000000000003  000400000002 R_X86_64_PC32     0000000000000000 .Lstr - 4
