R devel - Apr 2009 - R build fails during make when configured with "--with-x=no" (PR#13665)

If R is configured using the "--with=x=no" option, then the make fails
with the
following error:

make[4]: Entering directory

The problem appears to be with the "src/modules/Makefile".
Specfically, lines
26-29:

	@for d in "$(R_MODULES)"; do \
	  (cd $${d} && $(MAKE) $@) || exit 1; \
	done

Here, R_MODULES is blank, resulting in the "cd" command transferring
to the
user's home directory, where, of course, no Makefile is found resulting in
the
error above.

Work-around appears to be to simply disable loop if R_MODULES is empty.

(Even more "fun" would ensue if in fact there were a Makefile
there...)

Shell script and Make portability is a pain in the derriere, but
offhand, those double quotes just look wrong:

viggo:~/>for i in "" ; do echo $i; done

viggo:~/>for i in  ; do echo $i; done
viggo:~/>for i in "foo bar" ; do echo $i; done
foo bar
viggo:~/>for i in foo bar ; do echo $i; done
foo
bar

Notice that the versions with quotes invariably do the Wrong Thing....
