Test_cayley_even_odd_vec.c causes Grid compilation to fail

[ctpeterson]

Describe the issue:

My apologies for not bringing this up earlier, as I've been experiencing this issue for a few months now; however, I've simply just skirted around it whenever I compile Grid by having Grid not compile the Test_cayley_even_odd_vec.c test. The problem is as follows.

Whenever I try to compile Grid using the configure command that I've provided below, the compilation fails when it hits Test_cayley_even_odd_vec.c. There is not a helpful error message that prints out when it fails. The first line of the error message is as follows.

/usr/bin/ld: Test_cayley_even_odd_vec.o: in function `Grid::ZMobiusFermion<Grid::WilsonImpl<Grid::Grid_simd<std::complex<double>, double __vector(4)>, Grid::FundamentalRep<2, Grid::GroupName::SU>, Grid::CoeffComplex> >::ZMobiusFermion(Grid::Lattice<Grid::iVector<Grid::iScalar<Grid::iMatrix<Grid::Grid_simd<std::complex<double>, double __vector(4)>, 2> >, 4> >&, Grid::GridCartesian&, Grid::GridRedBlackCartesian&, Grid::GridCartesian&, Grid::GridRedBlackCartesian&, double, double, std::vector<std::complex<double>, std::allocator<std::complex<double> > >&, double, double, Grid::WilsonImplParams const&)':

If memory serves, there is an additional test that also fails that is part of the Zmobius test suite. Please let me know if you need more information.
