I had presented two different ways forward back when this was originally
discussed:

 [Handle different "struct stat" between GDB and BFD]
 [users/palves/stat branch]
 https://sourceware.org/legacy-ml/gdb-patches/2020-01/msg00608.html

 [use gnulib --avoid=largefile, let ACX_LARGEFILE handle enabling largefile support consistently
  throughout the tree]
 [users/palves/gnulib-largefile branch]
 https://sourceware.org/legacy-ml/gdb-patches/2020-01/msg00637.html

Back then IIRC, I was thinking that the --avoid=largefile solution
was the best one, but for some reason, the gnulib build fails with that,
which seemed like a gnulib bug.  Since you then said back then you didn't
really care for a solution to this problem, I ended up forgetting about
this whole issue and many of the details.  :-/

Thanks,
Pedro Alves
