For glibc, ldd on the target is but a simple script, and glibc installs a
ldd script (can't remember where, look in the sysroot, probably).

For uClibc, ldd is a C program, and crosstool-NG does not build or install
it. However, it should not be too difficult to build and install them as
part of the standard build.

Crosstool-NG, however, installs a ldd-like script that can be used the cross
way: call it as you call ldd, specify where the rootfs is, and it tries to
resolve dependencies. There are still limitations, though, but are about
missing --data-relocs, --function-relocs, --unused, and --verbose.
