When I tested gcc's behaviour before, I forgot the extern "C", so it
would warn when the types *did* match.
So in the end
* __clear_cache takes two void pointers.
* aarch64 was correct before.
* libgcc's manual is wrong.
* this patch fixes arm.

Current gcc's produce an error if __clear_cache is anything but
__clear_cache(char *a, char *b);
It looks like we had just implemented a gcc bug that is now fixed.

AAPCS ABI Section 7.1.4 [1] specifies that va_list
should be defined as struct __va_list { void *__ap;};
And in C++, it is defined in namespace std.
