Both GCC and Clang use x87 instructions by default on 32-bit x86 targets, but the loss of precision resulting from that has yielded crashing tests (see referenced issue), and it can be safely assumed there are very few CPUs that both don't support SSE2 and are expected to run SolveSpace This commit also removes a now-redundant check for 32-bit Windows against TARGET, which doesn't seem to be actually set by CMake at all Ref: #565
