Subject: [PATCH] Makefile: fix parallel build failure

At the moment parallel build fails due to 2 causes:
1) parsetime.l tries to include incomplete y.tab.h, since y.tab.h is the
result of yacc -d parsetime.y
2) when compiling y.tab.c, y.tab.c itself is not complete, since it is
the result of yacc -d parsetime.y

So fix it by:
1) making parsetime.l to wait for y.tab.h to be created by yacc
2) waiting for y.tab.c and y.tab.h to be created before compile them
