==== Gsl ====

Reduced optimization to "-O1", but with intel-compiler still fails LinAlg-unit test

 wget http://gnu.askapache.com/gsl/gsl-2.6.tar.gz
 tar -zxvf gsl-2.6.tar.gz
 ./configure --prefix=/usr/local CC=icc FC=ifort CXX=icpc FCFLAGS="-O1 -xcore-avx2" CFLAGS="-O1 -xcore-avx2" CXXFLAGS="-O1 -xcore-avx2" --enable-shared=no
make -j 16
make check

Libint2
