automake >= 1.11.4 aclocal misses ../share/aclocal

[Ralf Corsepius]

Hi,

automake >= 1.11.4 doesn't create $(datadir)/aclocal.

This cause aclocal to fail:

tar xvf automake-1.11.4.tar.xz
cd automake-1.11.4
configure --prefix=/tmp/foo
make
make install

Change to the source directory of an arbitrary automake-based package 
and run
/tmp/foo/bin/aclocal

aclocal: couldn't open directory '/tmp/foo/share/aclocal': No such file 
or directory

$(datadir)/aclocal is the directory, packages outside of automake are 
supposed to install their *.m4's into.

It's an error
a) of automake to not create this directory
b) in aclocal to abort in case this directory is not present
