makefiles: deduplicate main target name into new PROG var

Put the main target name into a new PROG variable, put PROG into a new
TARGET variable, make "all" depend on `$(TARGET)` and replace every
other occurrence of the main target name with `$(PROG)`.

On the makefiles that build non-shared objects, to make them more
similar.  With this commit, all of their targets are identical (except
for the extra "lib" target on src/lib/Makefile).
