[Rd] Build R with MKL and ICC

[Nathan Kurz]

Hi Arnaud --

I'm glad it's working for you.  I'm not sure I understand your final
answer.  Are you saying that the version I posted worked for you as
given, or that you had to remove some of the other options?

Perhaps you could post the full final recipe in a way that others can
copy and paste if they find this thread in the future?

Also, did you determine if the the same approach worked for linking to
MKL worked when using a non-Intel compiler?   That is, can you
substitute the gcc or clang tool names and get the same result?
