New exp10f version without SVID compat wrapper
This patch changes the exp10f error handling semantics to only set
errno according to POSIX rules.  New symbol version is introduced at
GLIBC_2.32.  The old wrappers are kept for compat symbols.

There are some outliers that need special handling:

  - ia64 provides an optimized implementation of exp10f that uses ia64
    specific routines to set SVID compatibility.  The new symbol version
    is aliased to the exp10f one.

  - m68k also provides an optimized implementation, and the new version
    uses it instead of the sysdeps/ieee754/flt32 one.

  - riscv and csky uses the generic template implementation that
    does not provide SVID support.  For both cases a new exp10f
    version is not added, but rather the symbols version of the
    generic sysdeps/ieee754/flt32 is adjusted instead.

Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
powerpc64le-linux-gnu.
