But this is not automatic. When typing

  $CC program.c -o program -lmpfr -lgmp

(where $CC can be gcc, tcc or icc, for instance), things should just
work, i.e. the correct options should be passed to ld *by default*.

Perhaps defining the LD_RUN_PATH environment variable instead of
LD_LIBRARY_PATH could be a workaround, but gold does not support
it, so that this cannot be a general solution.

Moreover, what path should be given when the library is on NFS, where
the mount point (e.g. $HOME directory) depends on the machine?

Note that it is important that several machines can be used at the
same time, e.g. for parallel computing on a network of machines.

libtool is used to compile libraries, but in general, the user does
not use it to build an executable.
