gpio tools fail to build correctly with make parallelization: $ make -s -j24 ld: gpio-utils.o: file not recognized: file truncated make[1]: *** [/home/labbott/linux_upstream/tools/build/Makefile.build:145: lsgpio-in.o] Error 1 make: *** [Makefile:43: lsgpio-in.o] Error 2 make: *** Waiting for unfinished jobs.... This is because gpio-utils.o is used across multiple targets. Fix this by making gpio-utios.o a proper dependency.
