Use LIBS instead of LDFLAGS (and respect LDFLAGS from env.) for libraries about skipfish

[GoogleCodeExporter]

The Makefile currently passes LDFLAGS at the end of the $(CC) line, so I do not 
see 
the problem in the context of that doc? 

Your patch just renames LDFLAGS to LIBS.

I mean, you could just as easily keep LDFLAGS named as-is, and include env 
ADD_LDFLAGS 
for your needs, but I don't understand what this is trying to accomplish - if 
something distro-specific, why not just apply a patch to add the options you 
want?

[And for what it's worth, I'm pretty sure that --as-needed makes absolutely no 
difference for skipfish, as it does not come with any elaborate linking 
dependencies.]

The general part:

It makes sense to respect standard environment variables and when you can add 
+= and
?= operators to Makefile, it's also easy... there's no need to "invent" more 
names
for them.

The distro specific part:

The LDFLAGS come from the /etc/make.conf gentoo-distro specific file to the 
package
manager (Portage, in this case) and gets exported to environment for 
build-time. So
when I have LDFLAGS="-Wl,--as-needed" in /etc/make.conf, I expect every single
package to use it.

That said, there's likely not much gain for you as upstream to add this feature 
to
skipfish, but I'm asking you still do, just to make it compatible with Gentoo's
standards and we can easily include your software :)

Thanks!

Just some example,

http://sources.redhat.com/automake/automake.html#Standard-Configuration-Variable
s

e.g. -D flags go to CPPFLAGS += -Dsomething
optimization flags for CC go as CFLAGS += -O3 -g -ggdb
extra LDFLAGS go as LDFLAGS += -Wl,-something
default CC goes as something like CC ?= gcc

Then

$(CC) $(LDFLAGS) $(CFLAGS) $(CPPFLAGS) $(objects-variable) $(libs-variable)

Ok, thanks for the explanation. The upcoming version will honor external 
CFLAGS, 
LDFLAGS, just pending some other bugfixes.
