Why ldd(1) launches linux apps?

[Artem Belevich]

lss just sets TRACE_LOADED_OBJECTS environment variable and then execs
the binary.
FreeBSD's dynamic linker then checks for that variable and, if set,
just prints out loaded objects and then exists.

When you run ldd on a linux binary, it's *Linux* dynamic linker that
gets launched and it may have different way of triggering the trace.

That said, ldd seems to work fine on linux binaries on FreeBSD-7, but
does indeed launch linux binary in 8-STABLE, so something has changed.

If you do 'env LD_TRACE_LOADED_OBJECTS=1 /compat/linux/bin/cp' on
8-STABLE it still works fine.
