I would like to mention here that key work is to report and explain that

that will need the -fcommon option. That's the biggest effort in my
opinion.
For this, it would help to update the porting-to web page. Wilco had a
first version of such a patch at:
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg02662.html – I think it
should be reviewed and eventually committed.
(Regarding the changes.html change, I think it should be under "C" and
not under general improvements; as far as I can see, it only affects C
(and ObjC?), even though the flag is also used for
lto_symtab_resolve_replaceable_p and in ada/gcc-interface/utils.c.)
