'_' is used in Makefile variable names and many variables end with
"^# name". Relax sort-makefile-lines.py to allow '_' in name and
"^# name" as variable end. This fixes BZ #31385.

for cmp_to_key() to work correctly across all comparisons.

The scripts/sort-makefile-lines.py script sorts Makefile variables
according to project expected order.
The script can be used like this:
$ scripts/sort-makefile-lines.py < elf/Makefile > elf/Makefile.tmp
$ mv elf/Makefile.tmp elf/Makefile
