FLAG_ELF_LIBC6 instead of FLAG_LIBC6.

I have not looked at this patch in detail.  I would prefer if we removed
unified cache support for libc.so.4, libc.so.5 and always wrote
FLAG_ELF_LIBC6 to the cache instead.  The older Linux libcs have been
obsolete for more than twenty years.  I do not know how much work this
would be, so if someone can review your patch and it can go in, that's
fine with me.

Thanks,
Florian
