If the installed libraries have libtool library files (those ending in
.la), then there is no need for -R.
Otherwise, passing -R in LDFLAGS for configure could screw some tests:
-R is not understood everywhere (except if you use libtool), and
configure tests do not use libtool usually.

I wouldn't want the user to use -R. If the libs are libtool libs, you
should be fine all along. Using installed libraries, with or without
libtool, the gnulib module havelib comes in handy.
Hope that helps.
Cheers,
