NCC compiler performance is subpar if compared to regular gcc/clang/msvc compilers.

I.e.: NCC compiler

time ./buildnativeoperations.sh -o aurora -t -j 24 1>out.ok 2>out.err

real    86m6.058s
user    1351m31.968s
sys     11m27.982s

GCC 7.4 compiler:

time ./buildnativeoperations.sh -a avx2 -t -j 24 1>out.ok 2>out.err

real    2m40.058s
user    52m52.287s
sys 1m53.943s
