Have you considered searching for uses of RPATH_ENVVAR?
$ grep RPATH_ENVVAR Makefile.in
RPATH_ENVVAR = @RPATH_ENVVAR@
# On targets where RPATH_ENVVAR is PATH, a subdirectory of the GCC build path
$(RPATH_ENVVAR)=`echo "$(TARGET_LIB_PATH)$$$(RPATH_ENVVAR)" | sed
's,::*,:,g;s,^:*,,;s,:*$$,,'`; export $(RPATH_ENVVAR); \
$(RPATH_ENVVAR)=`echo "$(HOST_LIB_PATH)$$$(RPATH_ENVVAR)" | sed
's,::*,:,g;s,^:*,,;s,:*$$,,'`; export $(RPATH_ENVVAR);
$(RPATH_ENVVAR)=`echo "$(TARGET_LIB_PATH)$$$(RPATH_ENVVAR)" | sed
's,::*,:,g;s,^:*,,;s,:*$$,,'`; export $(RPATH_ENVVAR); \
$(RPATH_ENVVAR)=`echo "$(HOST_LIB_PATH)$$$(RPATH_ENVVAR)" | sed
's,::*,:,g;s,^:*,,;s,:*$$,,'`; export $(RPATH_ENVVAR); \
