Building CSA fails due to missing `README`

[heplesser]

Attempting to build CSA on Linux fails because README is not present:

$ ./autogen.sh 
aclocal-1.13 -I /usr/share/aclocal
libtoolize --copy --automake
autoheader
autoconf
automake-1.13 --copy --add-missing
configure.ac:76: installing './config.guess'
configure.ac:76: installing './config.sub'
configure.ac:3: installing './install-sh'
configure.ac:3: installing './missing'
Makefile.am:4: warning: shell PYTHONPATH=$(srcdir: non-POSIX variable name
Makefile.am:4: (probably a GNU make extension)
Makefile.am: error: required file './README' not found
libpycsa/Makefile.am: installing './depcomp'

One either needs a symlink from README to the existing README.md, or tell automake that the readme file is called README.md. The problem also occurs with automake 1.14.

Under macOS, libtoolize is available as glibtoolize. The autogen.sh script should therefore contain

# libtoolize is glibtoolize on macOS
if [ `uname -s` = Darwin ] ; then
  LIBTOOLIZE=glibtoolize
else  
  LIBTOOLIZE=libtoolize
fi

and then

echo $LIBTOOLIZE --copy --automake &&
$LIBTOOLIZE --copy --automake &&
