It is a good idea.

The second line isn't needed. I checked the following versions:

        ./check "GNU ld version 2.17.50.0.6-5.fc6 20061020"
        ./check "GNU ld version 2.17.50.0.12-4 20070128"
        ./check "GNU ld version 2.15.92.0.2 20040927"
        ./check "GNU ld (GNU Binutils) 2.18.50.20070913"
        ./check "GNU ld (Linux/GNU Binutils) 2.18.50.0.1.20070906"
        ./check "GNU ld (GNU Binutils) 2.17.50.20070726-12 (SUSE Linux)"
        ./check "GNU assembler (GNU Binutils for Debian) 2.17.50.20070426"

and they work fine. Do you have more to add?
