[spp] [PATCH 1/3] makefile: fix problem of dependency is not checked

[ogawa.yasufumi at lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi at lab.ntt.co.jp>

Add `-MMD` to CFLAGS option in Makefiles in each of directory under
`src` for checking updated files while compilation. Without this
change, files changed after previous compilation are ignored and not
compiled.
