On v10.5.8 I'm seeing some redundant declaration warnings from
disas/s390.c and assumed we wouldn't want to fix/workaround the disas
stuff. Same for some exynos4 file.
Also some uninitialized buf2 in the Realtek NIC or so.
And test-thread-pool breaks due to undefined ___sync_fetch_and_add and
___sync_val_compare_and_swap.
With my setup long broken due to pixman, we never made any progress
fixing the main() mess - Stefan W. replaced asprintf in the command line
code but I'd rather get rid of that in some way similar to here:
