Hmm, I saw BFD_PLUGIN is set together with BFD_LINKER_CREATED, so the current
check in INTERWORK_FLAG should have covered this.  While it is not, so I guess
in some place bfd linker dropped the BFD_LINKER_CREATED bit.

Some search in the code, it looks to me we should also save "BFD_LINKER_CREATED"
in BFD_FLAGS_SAVED in bfd.c/bfd-in2.h?  I have made this change locally, and
these failures gone away on arm native ld check without regression.
