I have just got aware of this bug as it indirectly prevents gcc-8
removal and makes the GCC maintainer angry. In the future don't hesitate
to Cc: the debian-m...@lists.debian.org mailing list so that porters can
be aware of the issue.

My knowledge of ADA is very limited, so I am not sure I fully understood
the problem. However please find below a first workaround using the
-mxgot option to increase the size of the GOT and allow bigger jumps.
