 This sounds like something very weird and unlikely. But OK.

 Clearly that worked, or you wouldn't get the -lxxx message.

 If you build with 'V=1' on the command line, you'll see the full argument list
of the LD command.

 If you want actual help from us, provide all the details, i.e. your busybox
config and the build log (with V=1). Put it in a pastebin to avoid spamming the
list.
