Error building openoffice.org-2: cannot compute object file suffix

[Maxim Khitrov]

Hello,

Have a bit of a problem and no idea on what is causing it... When I
try to build openoffice.org I get the following error: "configure:
error: cannot compute suffix of object files: cannot compile". The
full output is below. This happens when building gcc-ooo. I looked in
config.log, but see no relevant information there, maybe I'm looking
in the wrong place. Here's my uname -a output:

FreeBSD poseidon.mxwerx.net 7.0-CURRENT FreeBSD 7.0-CURRENT #16: Thu
Aug 23 21:11:49 EDT 2007
max at poseidon.mxwerx.net:/usr/obj/usr/src/sys/POSEIDON  i386

I've built this system with a bunch of WITHOUT_ knobs in src.conf, so
maybe a required tool is not installed. However, I have no idea what
is actually needed. Can someone who is familiar with this software
please tell me what configure does at the "checking for suffix of
object files" step? Maybe that will help me figure out where things go
wrong.

Thanks,
Maxim Khitrov
