Do not wrap logf, log2f and powf nsz/math
The new generic logf, log2f and powf code don't need wrappers any more, they set errno inline so only use the wrappers on targets that need it. 2017-09-19 Szabolcs Nagy <szabolcs.nagy@arm.com> * sysdeps/ieee754/flt-32/e_log2f.c (__log2f): Define without wrapper. * sysdeps/ieee754/flt-32/e_logf.c (__logf): Likewise * sysdeps/ieee754/flt-32/e_powf.c (__powf): Likewise * sysdeps/ieee754/flt-32/w_log2f.c: New file. * sysdeps/ieee754/flt-32/w_logf.c: New file. * sysdeps/ieee754/flt-32/w_powf.c: New file. * sysdeps/i386/fpu/w_log2f.c: New file. * sysdeps/i386/fpu/w_logf.c: New file. * sysdeps/i386/fpu/w_powf.c: New file. * sysdeps/m68k/m680x0/fpu/w_log2f.c: New file. * sysdeps/m68k/m680x0/fpu/w_logf.c: New file. * sysdeps/m68k/m680x0/fpu/w_powf.c: New file.
