copying relocations in other sections that refer to local symbols
in the section being discarded. Those relocations will have to
be converted somehow; as of this writing I'm not sure that any of
the backends handle that correctly.
It is tempting to instead not discard link once sections when
doing a relocateable link (technically, they should be discarded
whenever we are building constructors). However, that fails,
because the linker winds up combining all the link once sections
into a single large link once section, which defeats the purpose
of having link once sections in the first place.
Also, not merging link once sections in a relocateable link
causes trouble for MIPS ELF, which relies in link once semantics
to handle the .reginfo section correctly. */
