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.
