GNU binutils是GNU交叉工具链中的一个源码包

# Use "dsofn" from dso-1 in a GOTPLT reloc, but hide it in a
# version script.  This will change the incoming GOTPLT reloc to
# instead be a (local) GOT reloc.  There are no other .rela.got
# entries.  This formerly SEGV:ed because .rela.got was created
# too late to have it mapped to an output section.

There are 15 section headers.*
