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 $(RPATH_ENVVAR); \
# This is the list of directories that may be needed in RPATH_ENVVAR
# This is the list of directories that may be needed in RPATH_ENVVAR
        "RPATH_ENVVAR=$(RPATH_ENVVAR)" \
