[Qemu-devel] [PATCH 15/15] Move definition of HOST_LONG_BITS to qemu-common.h |

Like the related macro TCG_TARGET_LONG, HOST_LONG_BITS can be determined
by the C preprocessor. It is also not used in Makefiles.
So there is no need to calculate it in configure, and it can be defined
in qemu-common.h.
