New symbol version for logf, log2f and powf without SVID compat

This patch changes the logf, log2f and powf error handling semantics
to only set errno accoring to POSIX rules. New symbol version is
introduced at GLIBC_2.27.

The old wrappers are kept for compat symbols.

ia64 needed assembly change to have the new and compat versioned
symbol map to the same function.

All linux libm abilists are updated.
