Make executes a directory rather than the executable on the PATH

[Alexander]

Description: Ubuntu 23.04
Release: 23.04

make:
  Installed: 4.3-4.1build1
  Candidate: 4.3-4.1build1
  Version table:
 *** 4.3-4.1build1 500
        500 http://gb.archive.ubuntu.com/ubuntu lunar/main amd64 Packages
        100 /var/lib/dpkg/status

If there is a directory on the PATH before an executable on the PATH and the makefile has "/bin/sh" as the path (which is the default if nothing is set). Then the directory is executed instead of
For example with

test :
 foo

And with the following layout

.
 |-folder2
 | |-app
 | |-foo
 | | |-data
 |-folder1
 | |-foo
 |-makefile

If folder2 is higher priority on the path. The make will try and execute folder2/foo which will fail. If any shell is set other than /bin/sh make will use the shell instead of executing things itself and it will succeed.

This is seems to be fixed upstream in https://savannah.gnu.org/bugs/index.php?57962
