kf6-kwallet's kwalletbackend hard-requires LibGcrypt 1.5.0 for PBKDF2 key derivation and the GPG-backed wallet format. Vendor both libraries under the full-fork model (committed source/, offline-reproducible) and add libgcrypt to kf6-kwallet's dependencies. Release tarballs ship a pre-generated configure and a config.sub that already recognises the *-redox triple, so no autotools regeneration is needed at cook time. libgpg-error supplies a generic pthread-backed gpgrt_lock_t for Redox via its build script; the test-only redox.patch (tms/times stub) is baked into libgcrypt's source and kept alongside for future version bumps. Promoted from the stale recipes/wip copies (now .disabled).
