tools build: Allow duplicate objects in the object list
It's sometimes useful to specify the object affiliation to multiple config options like: libperf-$(CONFIG_X86) += tsc.o libperf-$(CONFIG_AUXTRACE) += tsc.o while the object itself is linked only once. Adding the support for this and ignoring duplicate objects in the object list.
