I tried (sorry for the typo above in my message -fno-common was misspelled), 
but omitting -fno-common does not change the result:

cd lib/gis
make clean
make

However, using -fno-common works e.g. for 'libgrass_datetime':

OK are:
- libgrass_bitmap.dylib
- libgrass_datetime.dylib
- libgrass_btree.dylib
- libgrass_gproj.dylib
and more, the modules also link successfully against these libs.

So probably the compilation flags are right, but something wrong in libgis?
Or another flag missing or a flag in the wrong position?
