This patch makes flt-32 libm functions use libm_alias_float to define public interfaces (in cases where _Float32 aliases of those interfaces would be appropriate, so not for finitef / isinff / isnanf). Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/flt-32/s_asinhf.c: Include <libm-alias-float.h>.
