gnulib-tool: speeding up --create-testdir

[Bruno Haible]

The patch from 2007-01-14 to avoid "./configure; make" during --create-testdir
did most often not work. This should fix it.

2007-03-10  Bruno Haible  <address@hidden>

        * gnulib-tool (func_create_testdir): Treat MOSTLYCLEANFILES like
        CLEANFILES. Put spaces in each line of $cleaned_files, not only the
        first and the last.
