Rework CHANGELOG_CMD to touch/echo >&2 only as needed
Currently CHANGELOG_CMD issues a
touch ChangeLog; echo "Scary message" >&2
even if the file is already present. For example, when running `make
distcheck' the following is observed:
"
/bin/sh: ../../.changelog.tmp: Permission denied
git directory not found: installing possibly empty changelog.
...
/bin/sh: ../../.changelog.tmp: Permission denied
git directory not found: installing possibly empty changelog.
"
That in itself happens since srcdir is RO, thus shell redirection [to
srcddir/.changelog.tmp] fails. At the same time the latter message is
wrong and misleading since the file is already there, with the correct
contents.
Silence the permissing warning (/dev/null is our friend), and add
a simple `test -e .../ChangeLog || (...' prior to the touch/echo combo.
As we're here also update the message to be more generic, since there
are multiple other reasons why things can fail.
