binary package ships unnecessary makefile snippet

[Rolf Leggewie]

$ apt policy rustc-1.76
rustc-1.76:
  Installed: 1.76.0+dfsg0ubuntu1-0ubuntu0.24.04
  Candidate: 1.76.0+dfsg0ubuntu1-0ubuntu0.24.04
  Version table:

$ dpkg -L rustc-1.76 | grep mk
/usr/share/rustc-1.76/architecture.mk

architecture.mk does not need to be there. I did not inspect the other versioned rustc binary packages but would not be surprised if this applies to them as well.
