debug: 		 For debugging the runtime linking of an application:
debug: 			LD_DEBUG=token1,token2  prog
debug: 		 enables diagnostics to the stderr.  The additional option:
debug: 			LD_DEBUG_OUTPUT=file
debug: 		 redirects the diagnostics to an output file created using
debug: 		 the specified name and the process id as a suffix.  All
debug: 		 diagnostics are prepended with the process id.

debug: 		 For debugging the link-editing of an application:
debug: 			LD_OPTIONS=-Dtoken1,token2 cc -o prog ...
debug: 		 or,
debug: 			ld -Dtoken1,token2 -o prog ...
debug: 		 where placement of -D on the command line is significant,
debug: 		 and options can be switched off by prepending with `!'.
