Re: Building Clearsilver under LTIB

That didn't help; the offending compile options were still present.  I guess
the arguments only add "extra" options, they don't replace what's there.

I can build neo_cgi.so directly with the cross-compiler, but am I missing
some information by not running setup.py?  From the output, it didn't seem
like it was doing anything other than calling the compiler/linker.
