How can altivec not be supported when you use -mcpu=power8?

Does your assembler not support VMX and VSX maybe?
Is there some other configuration problem?
powerpc_vsx_ok does not test if you can use -mvsx. Instead, it merely
tests if the assembler can handle VSX at all. If you use GNU binutils
at least, you are supposed to use one that isn't much older than the
GCC you are using (on other platforms the user cannot always easily
get a fully working assembler and linker :-/ )
So what are you seeing without this patch?
