+Subject: [PATCH] Fix singlefilehost build in non-portable mode (#42415)
+
+The singilefilehost needs to follow the libraries build in terms of how
+it links to OpenSSL: if it's a non-portable build, the singlefilehost
+needs to link to OpenSSL via linker arguments.
+
+The installer also needs to have FEATURE_DISTRO_AGNOSTIC_SSL defined
+just like it is defined for the libraries build.
+
+Fixes: #41768
