remove german slides when english are available

Remove german slides if a completely translated english version is
available. For slides that have been translated to english, but do
not contain all the information of the german slides, the german
slides are still available. But they are only available for
reference. That will not be built.

-$ ar r libhello.a file1.o file2.o

-$ gcc -o hello hello.o libhello.a
-\end{lstlisting}
-\end{frame}
-
-\subsubsection{Dynamische Bibliotheken}
-
-\begin{frame}[fragile]
-\frametitle{Dynamische Bibliotheken}
-\begin{lstlisting}
-# Erstellen dynamischer Bibliotheken
-$ gcc -c -fPIC file1.c file2.c
-$ gcc -shared -o libhello.so file1.o file2.o
-# Gegen die Bibliothek linken
-$ gcc -o hello hello.c libhello.so
-# Versuchen Sie nun das Programm zu starten
-\end{lstlisting}
-\end{frame}
-
-\begin{frame}[fragile]
-\frametitle{Wir erinnern uns an den Dynamic Loader!}
-Also, entweder LD\_LIBRARY\_PATH setzen, oder nach /lib bzw. /usr/lib
-kopieren.
-\end{frame}
-
-\begin{frame}
-\frametitle{\textbf{P}osition \textbf{Independent} \textbf{Code}}
-Die Option -fPIC bewirkt die Erzeugung von ''position independent code''.
-Das heißt, es wird Code erzeugt, der zur Laufzeit an jeder beliebigen virtuellen
-Adresse lauffähig ist.
-\end{frame}
-
-\begin{frame}[fragile]
-\frametitle{SONAME}
-\begin{lstlisting}
-# Erstellen dynamischer Bibliotheken
-$ gcc -c -fPIC file1.c file2.c
-$ gcc -shared -Wl,-soname,libsayhello.so \
-               -o libhello.so file1.o file2.o
-\end{lstlisting}
-Die -soname Linker-Option bewirkt, daß beim Linken der Name
-''libsayhello.so'' eingetragen wird. Das heißt der Loader
-sucht beim Starten der Applikation nach einer Bibliothek mit
-dem Namen ''libsayhello.so''.
-\end{frame}
-
-\begin{frame}
-\frametitle{Namensgebung}
-\begin{itemize}
-\item linker name
-\item SONAME
-\item real name
-\end{itemize}
-\end{frame}
-
-\begin{frame}[fragile]
-\frametitle{Namensgebung}
-\begin{verbatim}
-libhello.so.1   -> libhello.so.1.0.2
-# New minor version
-libhello.so.1   -> libhello.so.1.0.3
-# New Major version
-libhello.so.2   -> libhello.so.2.0.1
-\end{verbatim}
-SONAME beeinhaltet die Majornumber. Der Symbolic Link mit
-der Majornumber(SONAME) zeigt normalerweise auf die Bibliotheksversion
-mit der aktuellsten Minornumber (real name).
-\end{frame}
-
-\begin{frame}[fragile]
-\frametitle{Namensgebung}
-\begin{verbatim}
-libhello.so -> libhello.so.1
-\end{verbatim}
-Oft wird auch ein Link ohne Versionsnummer angelegt, der auf die
-aktuellste Majornumber Zeigt. Man spricht hier vom sogenannten
-''linker name''.
-\end{frame}
-
-\begin{frame}[fragile]
-\frametitle{DT\_RPATH und DT\_RUNPATH}
-\begin{lstlisting}
-$ gcc -Wl,-rpath,/mypath -o hello hello.c \
-			libhello.so
-\end{lstlisting}
--rpath erzeugt per Default DT\_RPATH. Um DT\_RUNPATH zu erzeugen,
-benötigt man die Option --enable-new-dtags. Beispiel:
-\begin{lstlisting}
-$ gcc -Wl,--enable-new-dtags \
-          -Wl,-rpath,/mypath \
-          -o hello hello.c libhello.so
-# Was faellt bei folgendem Kommando auf:
-$ objdump -p hello | grep PATH
