I believe this is now fixed in Guile-Git:

  
https://gitlab.com/guile-git/guile-git/-/commit/1d7cc8cdb61fc231eca4291005ff74f3fb8ae502

You can give it a try for instance by first building Guix against the
latest Guile-Git:

  guix build guix \
    --with-git-url=guile-git=https://gitlab.com/guile-git/guile-git

and then clearing your cache and retrying the command above against that
freshly-built Guix:

  rm -rf 
~/.cache/guix/checkouts/o5kwpub222hrjpef5n2t7chjqb2rptwgkolyld3e6u7tvukuhjra
  /gnu/store/…/bin/guix build ppsspp \
    --with-git-url=ppsspp=https://github.com/hrydgard/ppsspp

If it works for you, I’ll cut a 0.5.2 Guile-Git release.

Thanks,
Ludo’.
