We might want to start exporting the alternative implementation under
GLIBC_PRIVATE names, so that we can find them in the dynamic symbol
table.  Then we could have an LD_DEBUG mode that prints these function
symbols, translated from the function addresses returned from IFUNC
resolvers.  I think this would be a really useful diagnostic tool.

Thanks,
