Improved cross-compilation with clang
With this patch I can cross-compile Linux kernel with clang and distcc.
Otherwise both remote compilation and local fallback fail like this:
cat > foo.c <<-EOF
int main(int argc, char **argv) { return 0; }
EOF
env DISTCC_HOSTS=127.0.0.1 distcc clang -c --target=aarch64-linux-gnu- -o foo.o foo.c
error: unknown target triple 'unknown', please use -triple or -arch
distcc[304773] ERROR: compile foo.c on 127.0.0.1 failed
distcc[304773] (dcc_build_somewhere) Warning: remote compilation of 'foo.c' failed, retrying locally
distcc[304773] Warning: failed to distribute foo.c to 127.0.0.1, running locally instead
error: unknown target triple 'unknown', please use -triple or -arch
distcc[304773] ERROR: compile foo.c on localhost failed
Linux' kernel makefiles specify the target arch with `--target=foo`,
and distcc expects `-target foo`, hence the problem.
Closes: #416
