I couldn't find the why yet, but i did find that the fact that we don't
autoreconf libtool causes it since libtool 2.4.4 is packaged with
automake 1.14.1.
In a project where host-libtool (i.e. autoreconfs) see:

output/target/usr/share/libtool/aclocal.m4 ->
[AM_AUTOMAKE_VERSION([1.14.1])dnl
(circa line 54)

Since libtoolize blindly copies this at some point libltdl
automatically-triggered autoreconf uses this version (actually
am__api_version='1.14' in line 35) to call it, hence breaking.

One solution would be to autoreconf libtool which doesn't seem
straightforward.
Another is to "hack" libtool and s/1.14.1/1.15/ + s/1.14/1.15/ that file
(tested to work).
We could also define ACLOCAL & co in the autotools infra, it shouldn't
hurt any package, though i haven't tested this.

In any case it seems to be a problem limited to squid only or we would
have seen more of these.

Regards.
