They can preprend their own directories to $LD_LIBRARY_PATH.

which, in turn, may break things. For instance, MPFR uses LD_RUN_PATH
temporarily in its configure script. But if the user uses -rpath,
LD_RUN_PATH will be ignored. And I don't think we should re-implement
all the libtool machinery for the configure script to guess what

That's more a libtool thing than an automake one, AFAIK.
