[patch] hook_functions: copy_exec should make directories in DESTDIR

I learned that 'copy_exec' does not make directories in the DESTDIR. I think it
should. See the attached patch.

Cause 'copy_exec' to create directories under DESTDIR

I'm having second thoughts... First I had it making ${DESTDIR}/$(dirname $1),
but now changed it to $(dirname $2). That won't work right if the $2 is not a
full path, right? It will strip the last element and thus will not always
create the right destination:

 copy_exec /usr/local/sbin/whatever usr/local/sbin

... won't do the right thing. Maybe we should not apply this after all.

I don't think it would be right to apply this for the reason you describe. However, in the intervening time copy_exec has gained the ability to leave out the second parameter, in which case it will create directories as needed, since then it is able to unambiguously determine the target directory. Your example would thus become just 'copy_exec /usr/local/sbin/whatever'.
