Makefile: simplify output of the libpath_template
If a platform lacks the support to specify the dynamic library path, there is no suitable value to give to the CC_LD_DYNPATH variable. Allow them to be set to an empty string to signal that they do not need to add the usual -Wl,-rpath, or -R or whatever option followed by a directory name. This way, $(call libpath_template,$(SOMELIBDIR)) would expand to just a single mention of that directory, i.e. -L$(SOMELIBDIR) when CC_LD_DYNPATH is set to an empty string (or a "-L", which would have repeated the same "-L$(SOMELIBDIR)" twice without any ill effect). Signed-off-by: Junio C Hamano <gitster@pobox.com>
