Looks like it; vl.c gets reported three times at the same locations so 3
arches have been compiled.

My test machine is down ATM, I can confirm later when it's up.

BTW for the patch

commit 884a0c7677cf8431d2a632673914994c2e01673d

    pcnet: remove dead nested assignment, spotted by clang
    
 #endif


if debugging is enabled, addr will now print a different value than
earlier.
