Base powerpc logbl compat symbols on __logb not logb.
Some powerpc logb implementations define a compat symbol for logbl based on logb, whereas libm_alias_double defines such a compat symbol based on __logb instead. This difference (logb is weak, __logb isn't) is enough to result in different installed stripped shared libraries. The difference in the installed libraries isn't significant, but first changing the compat_symbol calls helps make it possible to validate a subsequent change to use libm_alias_double by comparison of libraries, so this patch does such a preliminary change. Tested with build-many-glibcs.py for all its hard-float powerpc configurations. * sysdeps/powerpc/power7/fpu/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Define as compat symbol based on __logb, not on logb. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise.
