I agree with this change. I had done something similar 4 years ago:
https://patches.dpdk.org/project/dpdk/patch/20210808125139.3573701-6-thomas@monjalon.net/

My patch was also adding build types "debug" and "minsize".
Now that clang is fixed, I will work on it (requires fixes for minsize).

Your patch shrinks the build directory from 20G to 9G in my setup.

There is another call to the function config() for the ABI ref build
which requires to add the new ABI parameter:

-                       config $abirefdir/src $abirefdir/build $cross \
+                       config $abirefdir/src $abirefdir/build ABI $cross \
                                -Dexamples= $*
                        compile $abirefdir/build

Applied with this change, thanks.
