Yes, it avoids a fork-and-exec and this simplifies strace-style 
debugging of make+sh invocations that go awry.

I am not seeing the problem on my platform (Ubuntu 21.10, Xeon E3-1225 
v2); what platform are you using?

How are you viewing the 'make' output? Are you using M-x compile under 
Emacs, or something else?

Does the problem go away if you use 'make -Oline'?

Does the problem go away if you apply the attached patch to the GNU Make 
source code?
