Breakpoints can't be hit after starting debugging from the Makefile Tools Project Outline

[Yingzi1234]

More info:
This bug is reproduced on platforms Windows, Linux and Mac.

Repro steps:

1. Open any folder, for example clib repository.
2. Run the Makefile: Configure command.
3. Open the Makefile Tools Project Outline, set the build target to “all” and the launch target to “clib”.
4. Add a breakpoint in clib.c
5. From the Makefile Tools Project Outline, debug the selected target, and confirm that the breakpoint is hit.

Expected result:
Debug can succeed and breakpoints can be hit.

Actual result:
Debug can succeed but breakpoint cannot be hit.
