Weird bmake behaviour from within installworld

[Ollivier Robert]

Hello,

I'm source upgrading a machine from 9.2-RC3 up to stable/10.  buildworld, buildkernel and installkernel went fine.  "installworld" is failing with this weird issue:

/etc/{make,src}.conf
http://pastebin.com/hQxPJvML

Any idea?

I've been building world for years with these settings so I'm a bit surprised it is failing for 10.  Any idea why?  Did I missed something obvious?  Didn't see anything related to that in UPDATING.
