 the "+=" syntax works for makefiles.  I use it on a regular basis.  
 Here is a random example from a project:

   CFLAGS+=-I hw_include -I . -I ${RTOS_SOURCE_DIR}/include

 The trick is to set the RTOS_SOURCE_DIR (equivalent to TOP above) 
 correctly, but this is fairly standard.

 mostly out of hacking on EMC for awhile.

   Best of luck.
