AIX release builds broken

Starting 21 June release AIX builds have been failing.

e.g.

07:18:59 if [ ! -r node ] || [ ! -L node ]; then \
07:18:59   ln -fs out/Release/node node; fi
07:18:59 gmake: *** [Makefile:1417: node-v27.0.0-nightly20260621665daeb54c-aix-ppc64.tar] Error 2
07:18:59 Build step 'Conditional steps (multiple)' marked build as failure
07:18:59 Archiving artifacts

There's not a lot to go on here, but for a passing build the output would be

07:23:12 if [ ! -r node ] || [ ! -L node ]; then \
07:23:12   ln -fs out/Release/node node; fi
07:23:12 /opt/freeware/bin/python3 tools/install.py install --dest-dir 'node-v27.0.0-nightly20260620a17d2b8fe3-aix-ppc64' --prefix '/'

Builds on the test CI are generally passing, which would point to a part of the build that is only run for the release tar balls (during or just before running tools/install.py).

Opening this here instead of the Build WG repository as no changes have been made to AIX release machine in the time period when the builds started to fail.

Comienza con el objetivo fallido de Makefile en Makefile:1417 y tools/install.py, comparando la salida fallida de la versión de AIX del 21 de junio con el ejemplo que funciona. Sigue el paso release-tarball antes de tools/install.py; se considera terminado cuando la compilación de la versión de AIX se completa y produce el tarball.
