ok, I figured out how to get it to work. It's not broken (this time!)

The port cross gcc compiler(s) in freebsd are compiled with
--without-includes, which removes /usr/include from the search path.
So unless we specify it, it can't find anything in include paths.

However, if you do -I/usr/include, it is an absolute path. The sysroot
isn't applied to it.

One must use -I=/usr/include - then the sysroot stuff gets appended correctly.

So now I have dnsmasq and dropbear cross compiling successfully
against a freebsd-head mips sysroot.

Next up, lua and some tiny http server..

(And yes, we should also fix those linker scripts. :-)
