Michael Holzheu e767a2b99d build process: Fix parallel build for libutil

When building libutil in parallel, it can happen that the archive
file is created twice:

 $ cd libutil
 $ make -j
  ...
  CC      libutil/util_rec_example.o
  AR      libutil/libutil.a
  AR      libutil/libutil.a
  LINK    libutil/util_base_example

This can lead to the following build error:

 $ make -j OPT_FLAGS="-pipe"
   ..//libutil/libutil.a(util_path.o): In function `sys_mount_point':
   util_path.c:56: undefined reference to `util_proc_mnt_get_entry'
   util_path.c:60: undefined reference to `util_proc_mnt_free_entry'
   collect2: error: ld returned 1 exit status
   ../common.mak:232: recipe for target 'util_path_example' failed

The problem is that the following rule from common.mak is triggered in
the libutil directory:

 $(rootdir)/libutil/libutil.a: $(rootdir)/libutil
      $(MAKE) -C $(rootdir)/libutil/ libutil.a
 .PHONY: $(rootdir)/libutil

To prevent this rule, use the local "libutil.a" as dependency for the
example binaries.
