Explicitly add the required -m32/m64 to *FLAGS; this overrides any
arch-specific -m* flags that may have been appended by multilib-portage.
Even though -m32/m64 is now added to *FLAGS, -m32/m64 still has to be
explicitly added to CC and CXX due to wine's build system. For example,
winegcc saves the build-time value of CC and uses it at runtime.
