MSYS2: empty compile_commands.json when running from make target

[MerijnHendriks]

As the title says, when running from a make target using msys2's make package (https://packages.msys2.org/package/make), the compile_commands.json file is an empty array.

analyze:
    compiledb -n make

But when I run it from terminal directly, it produces a correct compile_commands.json:

$ compiledb -n make

I tried specifying the path directly (absolute, relative) and the file directly, but no dice.

A more clear example.

Folder structure:

project/
  include/
    ext.h
  src/
    main.c
  obj/
    main.c.o
  makefile

The makefile:

analyze:
    $(MAKE) -Bnwk debug | compiledb -o- | cat

Running through the make target:

$ make analyze
make -Bnwk debug | compiledb -o- | cat
[]

Running from the command line directly:

$ make -Bnwk debug | compiledb -o- | cat

  ],

 }

Using the mingw32-make package (https://packages.msys2.org/base/mingw-w64-make) instead solved my issue!
