prepare-32bit hook fails for meta (sub)packages

Discussed in #45987

Hey, i got a question.

I made a pull request to update mesa to version 23.1.6 (#45635), when i was in vacation. Everything went well.
Though yesterday i made a PR for mesa 23.1.7 (#45974), and closed the previous PR, to not flood the Pull requests, but i saw that mesa 23.1.7 i686 build in the workflow failed so i guessed it wasn't ready yet.

So i reactivated the PR for 23.1.6 which we knew went correctly before i close it. But the same bug for the Build packages (i686, i686, glibc, linux/386, 1) workflows happens for no reason:

cp: cannot stat '/destdir//mesa-ati-dri-23.1.7/*': No such file or directory
=> ERROR: mesa-ati-dri-23.1.7_1: post-install_80-prepare-32bit: 'cp -a ${PKGDESTDIR}/* ${destdir32}/' exited with 1
=> ERROR:   in hook() at common/hooks/post-install/80-prepare-32bit.sh:64
=> ERROR:   in run_func() at common/xbps-src/shutils/common.sh:21
=> ERROR:   in run_pkg_hooks() at common/xbps-src/shutils/common.sh:262
=> ERROR:   in main() at common/xbps-src/libexec/xbps-src-doinstall.sh:66

(this is the error i got for 23.1.7, but 23.1.6 gets the same error)

I'm unsure why it happens, especially for 23.1.6 because, again, it worked before i closed it.

If someone can help, it would be much appreciated.
