core: LOG() gcc 2.9x fixes

In gcc versions older then 3.0  ## before a variable argument
when the argument is empty will "eat" the _entire_ preceding
sequence of non-whitespace characters (not only the ',').
The fix just adds a space in front of ',' in all the macros calls
that use var args and ##.
