This causes a problem with rootless Podman. Rootless Podman remaps user IDs in the container to ones controllable for the current user outside. The -u option instructs Podman to use a specified UID in the container but does not affect the UID remapping. Therefore, the UID in the container can be remapped to some other UID outside the container. This can make the access to bind-mounted volumes fail because the remapped UID mismatches with the owner of the directories. Replace -u $(UID) with --userns keep-id, which fixes the UID remapping. This change is limited to Podman because Docker does not support --userns keep-id.

This commit introduces gdb_extend_qsupported_features, gdb_extend_query_table, and gdb_extend_set_table functions as interfaces to extend the qSupported string, the query handler table, and the set handler table, allowing target-specific stub implementations.
