Subject: [PATCH] build: Add a minimal configures script

When building libvterm with slibtool using the rlibtool symlink the
build will fail when the generated libtool is not found. This file is
required with rlibtool so that the build can determine if the build
should be shared, static or both.

This can be solved by adding a minimal configure script.

The build steps are now:

autoreconf -fi
./configure
make
make install
