Fix incorrect usage of `if defined(EIGEN_ARCH_PPC)` => `if EIGEN_ARCH_PPC`
This PR tries to fix an incorrect usage of if defined(EIGEN_ARCH_PPC)
in Eigen/Core header.
In Eigen/src/Core/util/Macros.h, EIGEN_ARCH_PPC was explicitly defined
as either 0 or 1. As a result if defined(EIGEN_ARCH_PPC) will always be true.
This causes issues when building on non PPC platform and MatrixProduct.h is not
available.
This fix changes if defined(EIGEN_ARCH_PPC) => if EIGEN_ARCH_PPC.
