libc/uClibc: do not install cross-ldd

I was unable to make the cross-ldd from uClibc to work, and
it is not possible to build it on non-POSIX system.

Besides, we have a generic script that is in the starting-blocks
to replace it, that will work for any C library, and also will
work on non-POSIX systems. Bonus!
