It won't. If you are cross-compiling you'll have to specify CC and LD manually, plus a host of other settings. We usually pick pretty sane defaults (which is why you can get away without running autoconf), but they're not going to be reasonable for cross-compiling. If you do go the non-autoconf route, you'd probably want to try building with "make uname_S=whatever" to override our defaults (see config.mak.uname for an idea of which uname variables we look at).

Autoconf couldn't even build a simple hello-world with the compiler you specified. So the first step would probably be to figure that out. What does config.log say?
