I believe the choice is arbitrary. All that really matters is the

In BFD, it's an option, controlled by elf_backend_want_plt_sym. Both
elf32-i386.c and elf64-x86_64.c set it to 0. So there is no reason
for gold to emit it as yet.
At the moment, in gold, symbols like _GLOBAL_OFFSET_TABLE_ and
_PROCEDURE_LINKAGE_TABLE_ need to be defined by the CPU.cc file. With
some more experience I hope that we can consolidate the CPU.cc files
