45bf954fbe Better define 'EXTBSS' to allow developer to memset() set it to zero on startup.

ffc06fcea3 Apple GEOS reserves beside the main app area at $4000-$C000 a secondary app area at $0C00-$2000. While it was an elegant idea to use that secondary area for overlays at the end of the day those 5 kB are just too small. So now overlays go at the end of the main area (as with GEOS 64/128). 
However the stack (usually 1 kB) can be securely placed in the secondary area without effort from the side of the developer. The rest of the secondary area (usually 4 kB) is made available to the developer as (uninitialized) 'EXTBSS'.

5cf9f585a6 In error or warning messages, output the name of the library if this is 
relevant. It's otherwise difficult to know what happens when ar65 is called
from within a makefile or similar.
