#5215: gitlab-ci is not checking installs for branches 3.0 and 2.5
-----------------------+---------------------------
 Reporter:  strk       |      Owner:  robe
     Type:  defect     |     Status:  new
 Priority:  blocker    |  Milestone:  PostGIS 2.5.8
Component:  buildbots  |    Version:  2.5.x
 Keywords:             |
-----------------------+---------------------------
 When using:

 ```
 make installcheck RUNTESTFLAGS=-v
 ```

 The RUNTESTFLAGS is fully set by user instead of being *appended_to*.
 This means the internal `--extension` switch won't be used, defeating the
 purpose of the `installcheck`.

 Note that this would work:
 ```
 RUNTESTFLAGS=-v make installcheck
 ```

 The gitlab-ci configuration in branches 2.5 and 3.0 is using the non-
 functional call, resulting in lack of install check and duplicated normal
 check.

 This was fixed from 3.1 onward, see commit
