It could be a portability bug in a new ‘scandir*’ procedure (see commit
fa73c1937364872560c509f02b3d7648a5bed006).

Could you either print the names that ‘scandir*’ returns at its call
site in (guix discovery) like this:

--8<---------------cut here---------------start------------->8---
diff --git a/guix/discovery.scm b/guix/discovery.scm
index 292df2bd9..2d7a1ffdb 100644
--- a/guix/discovery.scm
+++ b/guix/discovery.scm
@@ -50,7 +50,7 @@ DIRECTORY is not accessible."
   ;; Use 'scandir*' so we can avoid an extra 'lstat' for each entry, as
   ;; opposed to Guile's 'scandir' or 'file-system-fold'.
   (fold-right (lambda (entry result)
-                (match entry
+                (match (pk entry)
                   (("." . _)
                    result)
                   ((".." . _)
--8<---------------cut here---------------end--------------->8---

… and/or run ‘./pre-inst-env rpctrace guix build hello’ to see what’s
going on?

HTH!
