6d4e60e365 fix #481: ensure liblz4.a dependency for make all 
`make all` will trigger several sub-directory makefiles.
several of them need `liblz4.a`.
When built with `-j#`, there are several concurrent liblz4.a built

Make liblz4.a a dependency, which is built once,
before moving to sub-directory Makefiles
