Subject: [PATCH] tools: iio: Correctly add make dependency for iio_utils
Date: Fri, 18 Oct 2019 13:29:08 -0400

iio tools fail to build correctly with make parallelization:
$ make -s -j24
fixdep: error opening depfile: ./.iio_utils.o.d: No such file or directory
make[1]: *** [/home/labbott/linux_upstream/tools/build/Makefile.build:96: iio_utils.o] Error 2
make: *** [Makefile:43: iio_event_monitor-in.o] Error 2
make: *** Waiting for unfinished jobs....
This is because iio_utils.o is used across multiple targets.
Fix this by making iio_utils.o a proper dependency.

I realize that we don't really need the parallelization for tools
because it's so small but when building with the distro we want to use
the same make command and -j wherever possible.
This same issue also appears in the gpio tools so if this looks like an
okay approach I'll fix it there as well.
