bug#6246: 24.0.50; Circular dependencies in lib-src/Makefile.in

[Eli Zaretskii]

Building Emacs outside of the source tree triggers the following
warnings from Make:

  make[2]: Circular /home/e/eliz/bzr/emacs/trunk/lib-src/rcs2log <- /home/e/eliz/bzr/emacs/trunk/lib-src/rcs2log dependency dropped.
  make[2]: Circular /home/e/eliz/bzr/emacs/trunk/lib-src/vcdiff <- /home/e/eliz/bzr/emacs/trunk/lib-src/vcdiff dependency dropped.
  make[2]: Circular /home/e/eliz/bzr/emacs/trunk/lib-src/rcs-checkin <- /home/e/eliz/bzr/emacs/trunk/lib-src/rcs-checkin dependency dropped.
  make[2]: Circular /home/e/eliz/bzr/emacs/trunk/lib-src/grep-changelog <- /home/e/eliz/bzr/emacs/trunk/lib-src/grep-changelog dependency dropped.

I think the problem is that we have both VPATH and an explicit
dependency for these files in lib-src/Makefile.in.

I seen this but ignored it. These scripts doesn't seem to be very important, I 
never had any problems running an uninstalled emacs without them.  I don't use 
RCS, vcdiff seems to be used only for SCCS, and I didn't find any usage of 
grep-changelog.

I have checked in a fix.
