[R] automated libR location

[Prof Brian Ripley]

'library' in R has a different meaning: I've altered the subject to be 
more accurate 'libR'.

This is what R CMD SHLIB is for: it does all this for you in a portable way.

But if you want to DIY, you can use R CMD config to find out the 
appropriate linker incantation.

BTW, I think it is Octave that is out of step here: almost everything 
else uses some sort of 'foo-config' command, or pkg-config (and R 
provides a pkg-config file, so you should be able to do
pkg-config libR --libs
in the standard fashion, for an installed copy of R).

That's the other sense of 'library'.
