[gccsdk] cross-compiling using gcc5 on the host 2

There is also a mod required to the cfns.gperf file, which creates cfns.h, to make the output in the cfns.h file consistent .. this is in recipe/patches/gcc and is named gcc/cp/cfns.gperf


Again, I suspect, but cannot currently prove, this this will also be back compatible
