Creating statically-linked binary with Zig

[iacore]

Working Example

echo.kk:

fun main() : console ()
  println("hello")

To compile:

koka -v2 --cc="zigcc" --ccopts="-target native-native-musl -static" echo.kk
cd .koka/v2.4.0/gcc-debug/
zig cc *.o -target native-native-musl -o echo

Pain points

1. --cc=<bin> doesn't accept command prefix like zig cc; instead it treats argv[0] as "zig cc".
2. Even -v2 doesn't show the linking command.
3. No way to specify custom C linker.
4. No way to stop after compiling to C source. I need an "dry-run" option that outputs the command need to compile the project, so I can integrate Koka into other build systems.
