Make test fails at compiling rem2pi when using icc/ifort+MKL

[carlomontec]

I encountered an error while running make test in Ubuntu 16.04 using Intel compilers version 17.04 and MKL. Error seems to be at compiling the function rem2pi which makes me think is related to:

• Actually decouple special function (openspecfun) from base #22390
• RFC: Remove special functions from Base #20427

It was compiled with a checkout from the GIT repository release 0.6:

Version 0.6.1-pre.0
Commit dcf39a1 (2017-06-19 13:06 UTC)
Platform Info:
OS: Linux (x86_64-linux-gnu)
CPU: Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz
WORD_SIZE: 64
BLAS: libmkl_rt
LAPACK: libmkl_rt
LIBM: libimf
LLVM: libLLVM-3.9.1 (ORCJIT, skylake)

with a Make.user file as:

MARCH=native
USEICC = 1
USEIFC = 1
USE_INTEL_MKL = 1
USE_INTEL_MKL_FFT = 1
USE_INTEL_LIBM = 1

The relevant Error output was as follows:

The error does not appear when compiling with GCC and BLAS libraries.

rem2pi is now implemented in Julia. Maybe reopen if still an issue.
