Makefile: add $(srctree) to dependency of compile_commands.json target
[ Upstream commit 6fc9aacad49e3fbecd270c266850d50c453d52ef ]
When trying to build compile_commands.json for an external module against
the kernel built in a separate output directory, the following error is
displayed:
make[1]: *** No rule to make target 'scripts/clang-tools/gen_compile_commands.py',
needed by 'compile_commands.json'. Stop.
This is because gen_compile_commands.py was previously looked up using a
relative path to $(srctree), but commit b1992c3772e6 ("kbuild: use
$(src) instead of $(srctree)/$(src) for source directory") stopped
defining VPATH for external module builds.
Prefixing gen_compile_commands.py with $(srctree) fixes the problem.
Fixes: b1992c3772e6 ("kbuild: use $(src) instead of $(srctree)/$(src) for source directory")
