Description Farhan Ali 2024-05-13 23:05:41 UTC 
make 4.4.1 is showing some strange behavior when it comes to handling command line variables. Buildroot passes 'install_root' command line variable to the glibc build, this variable is processed in :

buildroot-2024.02.1/output/build/glibc-2.38-44-gd37c2b20a4787463d192b32041c3406c2bd91de0/build/config.make:

...
install_root = $(DESTDIR)
...

DESTDIR is empty
With make 4.4.1, install_root gets overridden in config.make
With make 4.2.1, install_root DOES NOT get overridden

Due to this overriding, glibc tries to install its artifacts in '/' which fails

Just adding this for reference:

make command-line variables cannot be overridden with simple assignment:
