This points out that we need some cleanups in tests/meson.build, as it's
getting a bit messy with some of the test using igt_desp and others
test_deps, but that's out of the sope of this series.

Seems like for autotools we already have it:

% ag -G Makefile atomic
tests/Makefile.am
93:gem_create_LDADD = $(LDADD) -lpthread -latomic
125:sw_sync_LDADD = $(LDADD) -latomic
