The A01 example fails to link with global libraries. The link command will say "Using global libs" but then put the list of granular libraries as a link option. Reason is that hadlist.gmk seems to set some variable which tells binmake.gmk to go back to granular libs.
The problem is now fixed in tag "exampleA01-V06-02-00". A list of kernel libraries was erroneously added to EXTRALIBS in hadlist.gmk.
