make failing, tabs are fine, missing separator

[Russell King]

Trying to do make on the app is failing.  Tabs for make files are good.  I am getting the following errors:

Makefile:23: *** missing separator.  Stop.

This happens right after the line: 

all:

    (cd src;$(MAKE)) 

in ./Makefile.  Also note, there is no subdir.mk and include.mk in main folder or the sub folder.  Here is my Makefile contents for the main Makefile and sub folder Makefile.

Thanks
Russ
