Indeed that dependency only affects Kconfig (and resulting .config)
dependencies - no ordering is implied.

To control the build order of packages, look at config/userspace/pkg_map
- the order of packages in the list defines the order the packages (if
enabled) are built.  In your case you need to have the gpu library
package(and any of its dependencies) listed before the egl library package.
