How can I do that? By extracting the source tar again?

The way this is being done right now is:

After all three are built, make install is run from build-gtk directory
only. And for other two, only relevant files are copied over to the
required locations as:

/usr/bin/emacs => /etc/alternatives/emacs => /usr/bin/emacs-28.0.90
(actual binary)
/usr/bin/emacs-28.0.90.pdmp
/usr/bin/emacs-lucid => /etc/alternatives/emacs-lucid =>
/usr/bin/emacs-28.0.90-lucid
/usr/bin/emacs-28.0.90-lucid.pdmp

The corresponding directories from native-lisp for each of them are
copied over as well to /usr/lib64/emacs/28.0.90/native-lisp/

This means the *.el and *.elc files from GTK3 build are used by the
other two.

These are the steps which happen after building all three:
%{buildroot}: the final destination from which the RPM package is
created, it is a chroot.
%{version}: 28.0.90 here
%{native_lisp}: /usr/lib64/emacs/28.0.90/native-lisp

# Remove versioned file so that we end up with .1 suffix and only one DOC file
rm build-{gtk,lucid,nox}/src/emacs-%{version}.*

cd build-gtk
%make_install
cd ..

# Let alternatives manage the symlink
rm %{buildroot}%{_bindir}/emacs
touch %{buildroot}%{_bindir}/emacs

# Remove emacs.pdmp from common (we copy it over in later steps)
rm %{buildroot}%{emacs_libexecdir}/emacs.pdmp

# Install emacs.pdmp of the emacs with GTK+
install -p -m 0644 build-gtk/src/emacs.pdmp
%{buildroot}%{_bindir}/emacs-%{version}.pdmp

# Install the emacs with LUCID toolkit
install -p -m 0755 build-lucid/src/emacs
%{buildroot}%{_bindir}/emacs-%{version}-lucid
install -p -m 0644 build-lucid/src/emacs.pdmp
%{buildroot}%{_bindir}/emacs-%{version}-lucid.pdmp

# Install the emacs without X
install -p -m 0755 build-nox/src/emacs
%{buildroot}%{_bindir}/emacs-%{version}-nox
install -p -m 0644 build-nox/src/emacs.pdmp
%{buildroot}%{_bindir}/emacs-%{version}-nox.pdmp

lucid_comp_native_ver=$(ls -1 build-lucid/native-lisp)
nox_comp_native_ver=$(ls -1 build-nox/native-lisp)
cp -ar build-lucid/native-lisp/${lucid_comp_native_ver}
%{buildroot}%{native_lisp}
cp -ar build-nox/native-lisp/${nox_comp_native_ver} %{buildroot}%{native_lisp}

In the native-lisp/*/preloaded directory there are 124 files, and the
following log has 113 lines which say (native compiled elisp). It is
same for all the 3 builds. This is what you were referring to, right?
