What does ldd bring that can't be already achieved? For example on my
host system:

    $ ldd /bin/bash
        linux-vdso.so.1 (0x00007ffea5be0000)
        libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x00007f2ea6fa0000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f2ea6f9a000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f2ea6da9000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f2ea7114000)

    $ LD_TRACE_LOADED_OBJECTS=1 /bin/bash
        linux-vdso.so.1 (0x00007ffd3d3a7000)
        libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x00007f46883cd000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f46883c7000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f46881d6000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f4688419000)

(yes, that's shorter to type, I guess?)

Yann E. MORIN.

I guess the main thing that it brings is that people know about "ldd"
in general, while nobody knows about LD_TRACE_LOADED_OBJECTS :)

I was not too fond of it, but it looks like we do install it for an
internal glibc-based toolchain, so meh...

Applied to master, thanks.
