make run-c not working

[mboersma]

Description of the bug

I've been trying to build the examples and managed to get my macOS box configured and building the C examples (maybe?), but make run-c fails.

% make build-c run-c
/Library/Developer/CommandLineTools/usr/bin/make -C examples/multi_capability-demo-clang/ clean
rm -rf bindings/
mkdir bindings/
/Library/Developer/CommandLineTools/usr/bin/make -C examples/multi_capability-demo-clang/ bindings

Error: failed to read input file

Caused by:
    No such file or directory (os error 2)
make: *** [run-c] Error 1
% ls ./examples/messaging-producer-demo/target
ls: ./examples/messaging-producer-demo/target: No such file or directory

To Reproduce

Run make install-deps-macos build-c successfully and then try make run-c.

Additional context

Seems like the build didn't work or didn't put the .wasm file in the expected target location.
