cross-ldd works just as ldd, but supports
other architectures. It is needed by dracut, for instance.
It is suffixed with "-ldd-buildroot" to avoid conflicts
with toolchains that already implement it.

Changes v1 -> v2:
  - simplified the download (suggested by Arnoult)
Changes v2 -> v3
  - changed the name to -ldd-cross, in order to avoid
    a conflict with the external toolchains that implement it
Changes v3 -> v4
  - No more Config.in. It is just a bind host-only package
  - cross-ldd.mk: added pointer to dracut documentation in
    the comment
  - Changed the suffix to -ldd-buildroot
  - No longer uses SED, but uses an actual patch for that
