Don't hard-code x86 specific names, use vdso_config definitions
to find the correct function matching the architecture.

Add random VDSO function names in names[][]. Remove the #ifdef
CONFIG_VDSO32, having the name there all the time is harmless
and guaranties a steady index for following strings.

This is indeed the right way of doing it. Thanks. I'll take this now,
though with one small fixup:

quoted

+	const char *version = versions[VDSO_VERSION];
+	const char **name = (const char **)&names[VDSO_NAMES];

I'll just do:

         const char *name = names[VDSO_NAMES][6];

Instead of referring to name[6] everywhere after. Seems more straight
forward.

Yes you are right that's more straight forward when using only one of 
the names.
I copy-pasted it from the gettimeofday test which uses several names 
from the table.
