Hi,
I noticed a Canadian cross failure in 4.8 which was down to BUILD_CXXFLAGS being set to ALL_FLAGS even when build != host.  Obviously this has only become apparent with 4.8.

Thanks,
Stu

	* configure (BUILD_CXXFLAGS): Set appropriately when build != host.
	* configure.ac (BUILD_CXXFLAGS): Likewise
