Here’s my powerful debugging trick for such dynamic binding issues (it’s
not related to offloading):
diff --git a/gnu/packages/commencement.scm b/gnu/packages/commencement.scm
index d0393ebe25..5ec7facd02 100644

(define* (kernel-headers-boot0 #:optional (system (%current-system)))
+ (when (string=? system "x86_64-linux")
+ (pk system)
+ (display-backtrace (make-stack #t) (current-error-port) #f 80))
(match system
("i586-gnu" hurd-core-headers-boot0)
(_ linux-libre-headers-boot0)))
That gives me this:

At that point, it looks like a déjà-vu to me. :-)
Should be fixed with efb10f175fa6323024aa471c58ea1da445085298.
