Looks like it was introduced in automake-1.4.  Quoting from the NEWS file:

* Added `AM_FOOFLAGS' variable for each compiler invocation;
  e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags

automake-1.5's documentation includes the same statement about INCLUDES being deprecated in favour of AM_CPPFLAGS as the latest docs do.
