Only give FDE encoding warnings if --eh-frame-hdr was specified.
This bug was observed on nios2-linux-gnu with some C++ programs
linked with -pie or -shared. The nios2 ABI doesn't include appropriate
relocations in this instance and GCC is also being patched not to pass
--eh-frame-hdr to the linker in those cases.
