+Subject: [PATCH] Makefile: Fix parallel build
+
+Sometimes mkdir $(SHARED_OUTDIR)/db races with compiler which is
+creating .o file in the same directory $(SHARED_OUTDIR)/db/db_bench.o
+
+Fixes error like
+
+| mkdir out-static
+| mkdir out-shared/db
+| Assembler messages:
+| Fatal error: can't create out-shared/db/db_bench.o: No such file or directory
