As means of investigating if lang/gcc6-aux has other problems
building on aarch64 than just __nonnull and __nonull_all I did:
# svnlite diff /usr/src/sys/sys/

The attempt to build lang/gcc6-aux (as part of attempting

vm_ooffset_t and vm_pindex_t has 2017-Feb-4 changes:
Revision 313194 - (view) (download) (annotate) - [select for diffs]=20

Define the vm_ooffset_t and vm_pindex_t types as machine-independend.
The types are for the byte offset and page index in vm object. They
are similar to off_t, which is defined as 64bit MI integer. Using MI
definitions will allow to provide consistent MD values of vm
object-related maximum sizes.

The "#define pid_t int" in the local:
/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/build/libiberty/config.h
likely messes up some later "typedef . . . pid_t;", such as:
=
/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/bootstrap/lib/gcc/aarch64-=
aux-freebsd12.0/6.3.1/include-fixed/sys/types.h:typedef __pid_t =
pid_t; /* process id */
resulting in:
typedef __pid_t int;
So lang/gcc6-aux bootstrapping has more problems than just __nonnull
and __nonnull_all issues, at least for aarch64 head.
lang/gcc6-aux might not be the only thing with such issues.
I stopped with this. There could be more issues for lang/gcc6-aux .
