I'm in the process of upgrading Poky to use libtool 2.2.2 and noticed
the echo problem. libtool.m4 was correctly added to aclocal.m4 though
and I didn't see the OBJDUMP problem.

To 'fix' the echo issue I added:

http://svn.o-hand.com/view/poky/trunk/meta/packages/libpng/libpng-1.2.16/makefile_fix.patch?rev=4267&view=markup

although I suspect echo = @ECHO@ might be better. I think libpng has
relied on old libtool behaviour which happened to export that and no
longer does so its a libpng bug but I'm open to more informed comments!

Cheers,
