unexpected EOF while looking for matching `"'

By comparing the old (working) makefile with the new one, I noticed that the new makefile had an " at the end of the line at the APP_INCLUDE_DIRS :=

By removing this " the error message unexpected EOF while looking for matching`"'disappears.

The excessive " can not be removed in the create-this-app file. If you do you get a unexpected EOF error for create-this-app instead.

So the solution is :

1) First run create-this-app form the Nios II EDS 9.1 command shell

2) Then edit the Makefile which is created by removing the last “ on the APP_INCLUDE_DIRS := line

I hope this may help others that have experienced a similar problem and it seems to be some mismatch here when upgrading from NIOS II EDS 9.0 to 9.1
