compile_commands.json is used by clangd[1] to provide code navigation
and completion functionality to editors. See [2] for an example
configuration that includes this functionality for VSCode.
It can currently be built manually when using kunit.py, by running:
./scripts/clang-tools/gen_compile_commands.py -d .kunit
With this change however, it's built automatically so you don't need to
manually keep it up to date.
Unlike the manual approach, having make build the compile_commands.json
means that it appears in the build output tree instead of at the root of
the source tree, so you'll need to add --compile-commands-dir= to your
clangd args for it to be found.
