It is possible to override $CC and $LD -- this should be enough for cross-compilation already. Note that the resulting binaries - even being foreign to the host architecture - may actually work just fine, using some emulator layer like qemu-user (www.qemu.org). So even build system tries to run executables it just built, the build process may complete successfully. Thanks, /mjt
