Even better you perform partial linking on each library and them make an archive of the two resulting object files. That way it operates like shared libraries would

You do partial linking with

gcc -r --nostdlib" so either instead of making the intermediate archive or after reextracting it, run gcc -r --nostdlib $CFLAGS $OBJECTS_A -o $LIBNAME_A.o gcc -r --nostdlib $CFLAGS $OBJECTS_B -o $LIBNAME_B.o 

then

ar -cr $LIBNAME_JOINED.a $LIBNAME_A.o $LIBNAME_B.o
