Add header file dependencies to build script.

After changing header files there are two options to rebuild
library:
 - rebuild library from scratch (using --clean flag)
 - manually delete affected object files and rebuild them.
This patch adds dependencies on header files to Makefile, for this
puporse option -MMD is used. The patch is tested with gcc and clang
compilers.
