So at least the problems with 'awk' and 'od' seem to be related somehow
to the kernels I built.
I found this by installing a stock 9.0/i386 on real i386 hardware (after
repairing said hardware -- it had not run in years) and finding it could
run the static-linked 'od' I had previously built without problems.
Curious I decided to cross-build the same source tree on the newly
installed 9.0 system and, perhaps without surprise, it generated an
identical binary for, e.g. 'od':
$ cd $MY_DESTDIR
$ cmp /future/build/woods/future/current-i386-ppro-destdir/usr/bin/od usr/bin/od
-r-xr-xr-x 2 woods wheel 244288 Apr 16 15:38
/future/build/woods/future/current-i386-ppro-destdir/usr/bin/od
-r-xr-xr-x 2 woods wheel 244288 Apr 26 02:36 usr/bin/od
$
Similarly 'awk' looks the same works just fine.
One of the kernels seems to be the same too, assuming one takes into
account the obvious difference in vers.o:
text data bss dec hex filename
20222422 515508 926144 21664074 14a914a
sys/arch/i386/compile/MONOLITHIC/netbsd

/future/build/woods/future/current-amd64-i386-ppro-obj/usr/src/sys/arch/i386/compile/MONOLITHIC/vers.o
However the other kernel I've tested is somehow not the same:
text data bss dec hex filename
4776885 80232 1347584 6204701 5ead1d
sys/arch/i386/compile/XEN3PAE_DOMU/netbsd

799 0 0 799 31f
sys/arch/i386/compile/XEN3PAE_DOMU/vers.o

/future/build/woods/future/current-amd64-i386-ppro-obj/usr/src/sys/arch/i386/compile/XEN3PAE_DOMU/vers.o
Next I'll try testing these kernels on Xen and the Soekris box.
