Description

In newer version of Libtool, ECHO variable is not set in
generated Makefiles, merely the lt_ECHO is. The ECHO
variable has never been documented nor meant to be used that
way without having independent M4 echo test in-code.

Available solutions:

1. Start generating snapshots that will
contain "./configure" & friends pre-generated
by your preferred version of GNU Autotools
which includes the undocumented ECHO variable
in generated Makefiles.

2. Start using CMake after 0.5 release.

3. Apply the patch in attachment to make the
code ready for latest versions of Autotools.

AFAIK code rebase to CMake is on its way, but IMHO the
change of build system does not prevent us from making
errors so please read the docs.
