I have already added a comment to that issue. I haven't marked this Debian bug as forwarded as I believe they are different bugs. Indeed, these are different, although interrelated, bugs.

For most architectures we are using the new "cs" backend (and will possibly migrate the remaining architectures). So it may not be possible to do the same kind of linking as was done with the old backend.
Bug#1065597: racket: Inclusion of mzdyn.o in the binary package
Package: racket Version: 8.10+dfsg1-2 Severity: wishlist Dear Maintainer, We are updating the Debian package for SWIG (a generator of scripting interfaces to C/C++ code), in order to include support for MzScheme/Racket. However, it does not work because the file mzdyn.o is needed and cannot be found anywhere. Indeed, this file is mentioned in the Racket documentation.[*] The SWIG's configure script try to find the path for that file by running this command: mzscheme --eval '(begin (require dynext/link) (with-handlers (((lambda args #t) (lambda args #f))) (for-each (lambda (x) (printf "~a" x)) (expand-for-link-variant (current-standard-link-libraries)' which yields: /usr/lib/racket/mzdyn.o Subsequently, the activation of the MzScheme support fails because this path does not exist. I see that, in the source for the Debian package racket, there is a file src/bc/dynsrc/mzdyn.c, that could be compiled into mzdyn.o and installed in /usr/lib/racket/. Do you think that this would be possible? Best, Rafael Laboissière [*] https://docs.racket-lang.org/inside/Writing_Racket_Extensions.html#(part._.C.G.C_.Extensions)
