PR26806, Suspected linker bug with LTO
This patch reverts most of git commit 1e3b96fd6cf, so IR symbols are
again not marked def_regular or ref_regular. That should be enough to
stop IR symbols from becoming dynamic. To mark as-needed shared
libraries referenced by IR symbols, use the referencing BFD rather
than the ref flags.

* elflink.c (elf_link_add_object_symbols): Don't set def/ref flags
for plugin syms. Do allow plugin syms to mark as-needed libs.
