Does the upstream repositories have the files or one requires extra patches ?
Please add a reference or two to bugzilla/gerrit or upstream where
these are available.

The following one liner should also work, correct ?
Feel free to name different from "ANDROID" and use that for the
_CFLAGS/_LIBS below.

               PKG_CHECK_MODULES([ANDROID], [cutils hardware sync])

Then this will become:

 AM_CFLAGS += -DHAVE_ANDROID_PLATFORM
+AM_CFLAGS += $(ANDROID_CFLAGS)
+libEGL_la_LIBADD += $(ANDROID_LIBS)
