I would say, GNU ld.  The innermost group ought to be repeatedly
searched until no new objects are extracted from libraries, before
looking at any other input files.  GROUP ( libtest2.a libdummy.a )
ought to cause head_dummy.o to be extracted from libdummy.a then
test2.o from libtest2.a, before the linker considers libtest.a.
