Had a quick look at this, this morning, and have what I think is a solution.
I'm using a current version of Linux Mint but should be close enough to the
Ubuntu base to work.
First I installed the -dev version of all the prerequisite libraries using
the Synaptic package manager (other package managers are available :-).
Be sure to install version 4 of the Allegro library, the newer version 5
is likely to lead to a world of pain.
I also installed the latest automake and autoconf packages. Automake is
definitely required at least.
Then I unpacked the tarball in a fresh working directory.
mkdir x
cd x
tar xzf ../ElkulatorV1.0Linux.tar.gz
Delete the symbolic links to the old automake version and replace with
links to the newer automake. I only installed the links required for the
build, you may need to adjust the version to that you have installed.
rm compile COPYING depcomp INSTALL install-sh missing
ln -s /usr/share/automake-1.16/{install-sh,missing,depcomp} .
There was a few iterations of ./configure && make here, but this is the
final result.
./configure
Edit the uef.c file and correct an over enthusiastic pointer indirection.
I guess earlier compilers where not as sharp on their type checking.
There are a lot of other compiler warnings about memory safety etc that
should also be corrected, but this is the one that is stopping compilation.
vi src/uef.c (use whichever text editor you are comfortable with)
Two lines to change as in this diff/patch.

Then edit the Makefile and add the maths library to the link list.
This is not the autoconf way to patch this and will be overwritten if
you run ./configure again.
vi src/Makefile
Just the one line this time.
