Subject: [PATCH] base: Added some extra logging macros

LOG, LOG_ERR.  LOG_ERR will always compile to a /stderr/ print.  LOG,
on the other hand, may not actually do anything if VERBOSE_LOGS is
not 1.  By default it is 0, so it must be defined when compiling to
enable - hence the adjustment of the Makefile.
