My guess about the issue was definitely wrong: simple tests
show that gmake and /bin/sh handle the notation that I
pointed at.

Looking at the log again: Further back there is a message
that I missed:
checking size of long long... checking for geteuid... checking for =
getc_unlocked... configure: error: in =
`/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/build/libiberty':

See `config.log' for more details.
yes
checking for putchar_unlocked... yes
gmake[3]: *** [Makefile:7409: configure-libiberty] Error 1
gmake[3]: *** Waiting for unfinished jobs....
Looking around that config.log shows problems like:
configure:5452: checking size of long long
configure:5457: =

And looking around for __nonnull in include files:
# grep -R __nonnull /usr/include/ | more
/usr/include/security/openpam_attr.h:# define OPENPAM_NONNULL(params) =
__attribute__((__nonnull__ params))
# grep -R __nonnull =
/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/bootstrap/lib/gcc/aarch64-=
aux-freebsd12.0/6.3.1/include-fixed/

aux-freebsd12.0/6.3.1/include-fixed/stdlib.h:int =
posix_memalign(void **, size_t, size_t) __nonnull(1); /* (ADV) */
So the __nonnull is from the bootstrap gcc 6.3.1 include-fixed area.
My guess is that __nonnull was intended to be a macro that expanded to =
an attribute
specification but the macro definition ended up missing for some reason.
The bootstrap gcc command above shows the results of my CFLAGS
and/or CXXFLAGS in case those are a problem (not that I expect
they would contribute to this specific issue).
I've started an update to other ports so even if they work it
will be a while before the Pine64+ 2GB completes that.
