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. * math/Versions (logf): New libm symbol at GLIBC_2.27. (log2f): Likewise.
