f7a0b063e7 Do not wrap expf and exp2f 
The new generic expf and exp2f code don't need wrappers any more, they
set errno inline, so only use the wrappers on targets that need it.
(If the wrapper is needed, then the top level wrapper code is included,
otherwise empty w_exp*f.c is used to suppress the wrapper.)

A powerpc64 expf implementation includes the expf c code directly which
needed some changes.

	* sysdeps/ieee754/flt-32/e_exp2f.c (__exp2f): Define without wrapper.
	* sysdeps/ieee754/flt-32/e_expf.c (__expf): Likewise
	* sysdeps/ieee754/flt-32/w_exp2f.c: New file.

5ab621c347 Move w_exp to libm-compat-call-auto 
This patch adds the "_compat" suffix to the wrappers of the function
exp, which use _LIB_VERSION / matherr / __kernel_standard
functionality.

Tested for powerpc64le, s390, and x86_64.

	* math/Makefile (libm-calls): Move w_exp...
	(libm-compat-calls-auto): Here.

	* math/w_expl.c: Add suffix "_compat" to filename.
	* sysdeps/ia64/fpu/w_expl.c: Likewise.
	* sysdeps/ia64/fpu/w_expf.c: Likewise.
