build: Enable Automake's dependency tracking.

build: Enable Automake's dependency tracking.

Quite often, after changing a struct defined in a .h file, I see "make check"
fail. After "make clean; make", "make check" passes again. This wastes my time.
Unlike 20 years ago, I don't want think about which .o files I need to erase
and rebuild. Build times are now much smaller than they were 20 years ago,
especially when configuring with --disable-shared and CFLAGS="-ggdb".
