OK, I updated the patches a bit more and now just holding them in
praiskup-ARFLAGS branch for a while.

I noticed that at this moment 'gnulib' decides what will be the default
ARFLAGS, not libtool (since the time libtool started to be dependant on
gnulib -- and thus calls automatically GL_EARLY).

To gnulib guys:  I haven't done proper analysis yet.  Is the
gl_PROG_AR_RANLIB really expected to be called for *each* 'gnulib'
dependant project?  If yes, could we possibly at least set the ARFLAGS
default value to 'cr' instead of 'cru'?  See [1,2] for context.

>From libtool POV I'm not sure what is correct approach, should we let
gnulib do the decission about ARFLAGS, or should I rather somehow by-pass
the gl_PROG_AR_RANLIB.  Similarly automake (theoretically, AFAIK it does
not depend on gnulib yet), there is also some logic regarding ARFLAGS
variable..
