buildworld fails on FreeBSD 7.x for HEAD from 19.04.2012

Hello!

I can't build world from recent sources (HEAD as of 2012.04.19 11:06:48 UTC) on 
a machine running FreeBSD 7.3. I know it's EoLed, but I have found information 
in getline(3) manual that this function first appeared in FreeBSD 8, so I 
presume that the problem is present also for FreeBSD 7.4 (which is still before 
EoL). I have confirmed that problem doesn't exists for FreeBSD 9.0.

Here's excerpt from build log:
