If the softmmu targets are not enabled, "make check-build" fails to
build the qtests (which could not be run anyway without softmmu binary).
And the softfloat tests can not be compiled with MinGW yet (the macro
LITTLEENDIAN is re-defined in one of the system headers there, so this
needs some work first before it can be compiled).
