Some programs, which produce output from given input (such as 'iconv' or
'diff') can use in the output the line termination convention they found
in the input. No command-line option required in this case.

Programs which produce output without input, such as hello, can either
accept a --binary option (whose effect is to invoke
SET_BINARY(fileno(stdout)) - see gnulib module 'binary') and have the
testsuite invoke the program with --binary. Or produce output with CR/LF
always, and have the testsuite use "tr -d '\015'" before the comparison.
