If headers_install is executed from a deep/long directory structure, the shell's maximum argument length can be execeeded, which breaks the operation with: | make[2]: execvp: /bin/sh: Argument list too long | make[2]: *** Instead of passing each files name with the entire path, I give only the file name without the source path and give this path as a new argument to headers_install.pl. Because there is three possible paths, I have tree input-files list, one per path.
