allow DEBUGFILES to be overridden via getenv()

Browse Source 
If getenv("DEBUGFILES") yields a value then it takes precedence over
sysconf.DEBUGFILES or sys.c's #define DEBUGFILES.  (It probably should
only be controlled via environment since it is not a system-wide
attribute, but I haven't taken out the SYSCF handling for it.)
