Makefile: fix TEXTILE immediate assignment

From GNU make manual:

"For the append operator, ‘+=’, the right-hand side is considered immediate if
the variable was previously set as a simple variable (‘:=’ or ‘::=’), and
deferred otherwise."

So we need to initialize TEXTILE:= otherwise further += are deferred in
submakefiles and DIR value is not correct. that's useful when there is
more than 1 file to process..
