Subject: [PATCH] guix: Fix guile-ssh detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

See the upstream patch commit message. guile-ssh 0.18 inadvertently
changed the make-session API in a way that broke Guix’s configure-time
version check. This means Guix was built without guile-ssh support since
the guile-ssh upgrade, but ‘guix offload’ was broken anyway due to the
dlopen issue fixed in the previous commit.
