feature requests: $(__FILE__) and $(__LINE__) textual macros

[Basile Starynkevitch]

Hello

For non-trivial GNUmakefile-s on Linux it would be nice to have a 
$(__FILE__) and $(__LINE__) textual macros of GNU make.

They would behave as their equivalent __FILE__ and __LINE__ of the Cpp 
preprocessor.

On Linux Debian trixie/sid x86-64, my GNU make is
% /usr/bin/make --version
GNU Make 4.3
Built for x86_64-pc-linux-gnu

I do have a buggy non-trivial GNUmakefile
in 
https://github.com/RefPerSys/RefPerSys/blob/6f133cdfe044d652b394b7402f020d976336d72f/GNUmakefile

FYI, RefPerSys on https://github.com/RefPerSys/RefPerSys/ is a GPLv3+ 
licensed inference engine project. RefPerSys meaning "reflective 
persistent system".

Your opinion is appreciated on this new feature requests.

Regards from near Paris in France.
