redbear-ci / check (push) Has been cancelled
Details
libs: vendor libgcrypt 1.11.1 + libgpg-error 1.55; wire into kf6-kwallet 
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).
