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
