[Rd] Intel MKL compiling issue

[Cohn, Robert S]

> I would appreciate any insights over compiling R 3.4 with Intel MKL -- I have been successful until R 3.3.3 but now it stops complaining about pcre though it worked without Intel MKL as follows,

I successfully built R-rc_2017-04-19_r72555.tar.gz with icc & MKL on centos 7 with this:

export ICC_OPT="-mkl -xHOST -fp-model strict"
export CC="icc $ICC_OPT"
