+Subject: [PATCH] Makefile: fix tests dependencies
+
+librttest is listed in $(LIBS) so all tests must depend on librttest.a.
+Fixes build failures like:
+
+.../armv7-ctng-linux-gnueabihf-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64   -Os -g2  -o hackbench hackbench.o -lrt -lpthread -lrttest -L.
+.../armv7-ctng-linux-gnueabihf/bin/ld: cannot find -lrttest
+collect2: error: ld returned 1 exit status
