On my laptop -- running -current from a day or two ago -- I can't build
a new system.  On a desktop, running -current from about Aug 19, I can.
Both have up-to-date source trees; in both cases, I removed the entire
build directory before invoking build.sh.  I invoke build.sh via the
identical shell script on both machines.

On the failing machine, I get this while building the toolchain:

It looks as if 'make' isn't invoking the shell properly on the laptop
for that command.  (Both machines have /bin/ksh as root's shell.)

I see nothing in /etc/mk.conf that's even vaguely relevant; virtually
all of it has to do with pkgsrc.
