Presumably bin/libx.o was not compiled by a current version of gcc.
This error means that the linker did not understanding something in the
exception frame information.  gcc has asked the linker to create an
exception frame header, but, because there is something wrong, the
exception frame header will not be created.

I think everything will still work more or less correctly.  The effect
is that throwing an exception will take longer at runtime.

You can dump the exception frame information using readelf
--debug=frames.
