Use libm_alias_double for dbl-64 logb.
This patch makes dbl-64 logb use libm_alias_double. Both the dbl-64
and dbl-64/wordsize-64 versions are changed, and the ldbl-opt version
is removed. Because of multiarch wrappers, the changed
implementations are made not to define aliases at all if __logb is
defined as a macro, as with other functions, so avoiding duplicate
compat symbols while allowing those wrappers to be simplified.
Tested for x86_64, and verified with build-many-glibcs.py that
installed stripped shared libraries are unchanged (except on alpha
where changes from using the wordsize-64 version are expected).
* sysdeps/ieee754/dbl-64/s_logb.c: Include <libm-alias-double.h>.
(logb): Define using libm_alias_double, only if [!__logb].
* sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c: Include
<libm-alias-double.h>.
(logb): Define using libm_alias_double, only if [!__logb].
* sysdeps/ieee754/ldbl-opt/s_logb.c: Remove file.
* sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb-ppc32.c
(weak_alias): Do not undefine and redefine.
(strong_alias): Likewise.
* sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb-ppc64.c
(weak_alias): Likewise.
(strong_alias): Likewise.
