There is no good reason to invoke checkincludes.pl via GNU Make
in the first place.
A better solution is to do it by a shell script
or to make checkincludes.pl traverse the
subdirectories by itself.
[1] An easy solution
Add scripts/checkincludes-all:
#!/bin/sh
find . -name '*.[hcS]' -type f -print | sort \
| xargs $(dirname $0)/checkincludes.pl
Then, remove the 'includecheck' target from the Makefile.
You can do 'scripts/checkincludes-all'
instead of 'make includecheck'.
[2] A better solution
Extend scripts/checkincludes.pl so that it checks
all *.[hcS] files under the current directory
when no argument is passed.
You can simply do 'scripts/checkincludes.py'
