I have installed this on a second system with the same results:
╰─➤ gmake setup
/bin/sh: git: not found [No such file or directory]
/bin/bash: line 1: uname: command not found
make-rules/shared-macros.mk:140: /make-rules/ips-buildinfo.mk: No such file or directory
gmake: *** No rule to make target '/make-rules/ips-buildinfo.mk'. Stop.

The new make version seem to have problems with its environment. I don't know what makes my installations special as I try to be as close as possible to the build server. So I expect similar problems when I merge this PR.

@AndWac please paste output from following commands:

pwd
pkg list -afv gnu-make
gmake --version
git rev-parse HEAD
git status
env - gmake setup

Okay, I reproduced the problem. When gmake is run without env - then it fails here too. Investigating...

It looks like the following change introduced in GNU make 4.4 is causing the problem:

* WARNING: Backward-incompatibility!
  Previously makefile variables marked as export were not exported to commands
  started by the $(shell ...) function.  Now, all exported variables are
  exported to $(shell ...).  If this leads to recursion during expansion, then
  for backward-compatibility the value from the original environment is used.
  To detect this change search for 'shell-export' in the .FEATURES variable.

Namely, the problem is with the PATH variable.

To solve the problem we need some changes and cleanups in our Makefiles. Until they are implemented I'll convert this PR to draft.
