This patch simplifies pie build. Main change is replaces explicit rules by implicit which reduces Makefile size and makes it more readable. Notes: 1) intermediate build files are preserved. 2) Both blobs are linked with util-net.o. Restorer blob doesn't require it, but this allows to avoid explicit rule for it. v3: 1) Fixed parasite build. 2) Fixed blobs deps - %.bin and %.bin.o can now be build in parallel. 3) Updated restorer link: restorer is not linked with util-net.o anymore.
