On 32-bit systems size_t is identical unsigned in, causing redefinition errors in tables (Array_I_S). This patch guards against the 32-bit redefinition and defines Array_I_S = Array_I_U for the python interface if not already defined. Applies debian patch size_t_int32.patch https://salsa.debian.org/science-team/netgen/-/blob/d7ca1c564d90d00ce3d83e0b63c36fbec11cf1ce/debian/patches/size_t_int32.patch Fixes NGSolve#168
Extends support of non-intel architectures which do not have an RDTSC timer. Applies debian patch support-non-x86.patch https://salsa.debian.org/science-team/netgen/-/blob/d7ca1c564d90d00ce3d83e0b63c36fbec11cf1ce/debian/patches/support-non-x86.patch

change has no effect, NGCORE_HAVE_RDTSC is only ever defined if NETGEN_ARCH_AMD64 is defined.
