unable to build netbsd-7 on -current

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

(is this the right list?)

Building -7/amd64 on -current/amd64 fails with:

...

Sure enough:

$ file /scratch3/prlw1/netbsd-7/destdir/usr/lib/../lib/i386/crti.o
/scratch3/prlw1/netbsd-7/destdir/usr/lib/../lib/i386/crti.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), for NetBSD 7.0, not stripped

Earlier:
--- /scratch3/prlw1/netbsd-7/destdir/usr/lib/i386/crti.o ---
#   install  /scratch3/prlw1/netbsd-7/destdir/usr/lib/i386/crti.o
/scratch3/prlw1/netbsd-7/tools/bin/x86_64--netbsd-install -U -M /scratch3/prlw1/netbsd-7/destdir/METALOG -D /scratch3/prlw1/netbsd-7/destdir -h sha256 -N /scratch3/prlw1/netbsd-7/src/etc -c  -r  -o root  -g wheel  -m 444   crti.o /scratch3/prlw1/netbsd-7/destdir/usr/lib/i386/crti.o

but I don't actually see its build line, just:
--- /scratch3/prlw1/netbsd-7/destdir/usr/lib/i386/crti.o ---


Just in case, I:
- removed all files from the src tree as found by "cvs update -I!"
- moved /etc/mk.conf out of the way => must be defaults
- deleted objdir, destdir and tooldir

Built using:
d=/scratch3/prlw1/netbsd-7
sh build.sh -j9 -U -o -T ${d}/tools -O /tmp/obj -D ${d}/destdir build

Thoughts?

Cheers,
