relocatable-script: minimize dependencies

[Bruno Haible]

A package that needs relocatable-script does not need the gl_RELOCATABLE
machinery for relocatable _programs_, nor does it need any AC_DEFINEs.
Therefore I'm simplifying the dependencies like this:

2007-03-03  Bruno Haible  <address@hidden>

        * modules/relocatable-script (Files): Add doc/relocatable.texi,
        m4/relocatable-lib.m4.
        (Depends-on): Remove 'relocatable'.
        (configure.ac): Add gl_RELOCATABLE_NOP.
