New error message for coff-linker

["Philippe De Muyter" <phdm@macqel.be>]

Hello Ian

Could you please put the following patch in the binutils sources.  It
prevents a `core' file and gives an explanatory message for some
bad .o files generated by the sysV68's native `as'.  A similar warning
is already in objdump.

Thanks

Philippe
