This is how we build R with the Intel compilers and MKL on CentOS 6.x,
with different versions of R (latest version: 3.2.1) and Intel compilers
(latest version: 2015.3) on Intel SandyBridge CPUs:

fast="-ip -O3 -opt-mem-layout-trans=3 -xHost -mavx"
export CC="icc"
export CFLAGS="$fast -wd188 -fp-model precise"
export F77="ifort"
export FFLAGS="$fast -fp-model precise"
export CXX="icpc"
export CXXFLAGS="$fast -fp-model precise"
export FC="ifort"
export FCFLAGS="$fast -fp-model precise"

./configure --prefix=$destdir --with-blas='-mkl=parallel' --with-lapack

Thank you for this configuration. Nothing about openmp?

What about my cited missing librairies.

Any idea why they are not listed by the ldd command?

## Notes (they might not be true anymore):
## -static and -ipo break compilation
## -no-prec-div breaks make check
## -fp-model precise is needed for make check
## -wd188 removes a lot of warnings (see R Inst. & Adm. manual)

We have successfully used this setup for a couple of years now.
