Building Zig applications on sim:x86_64 with Zig 0.13.0 fails because the generated target "x86_64-freestanding-sysv" is not recognized by Zig. Introduce a Zig-specific ABI mapping that translates "sysv" to "gnu" without affecting other toolchains. After correcting the target ABI, linking still fails due to unresolved references to __zig_probe_stack. Add -fcompiler-rt so Zig includes the required compiler runtime during linking. Verified on sim:nsh with CONFIG_EXAMPLES_HELLO_ZIG=y: nsh> hello_zig [sim]: Hello, Zig! Fixes #19475 Signed-off-by: Ansh Rai <anshrai331@gmail.com>
