9.0/i386 build failure

[Michael W. Lucas]

I suspect I'm building on a system that's too old, but it's worth
asking.

FreeBSD eyeball.lodden.com 9.0-CURRENT FreeBSD 9.0-CURRENT #0: Sat Aug 29 00:31:14 EDT 2009     mwlucas at stretchlimo.blackhelicopters.org:/usr/obj/usr/src/sys/GENERIC  i386

csup today.  no /etc/src.conf, /etc/make.conf only contains a perl
definition.
