This is for nsz/math2 branch.
 
This is to support compiling e_exp2f.c more than once for multiarch.

	* sysdeps/ieee754/flt-32/e_exp2f.c [__exp2f] (__ieee754_exp2f,
	__exp2f_finite, exp2f): Skip.

i figured out how to update a branch so nsz/math == nsz/math2 now.

shall i do this for all new functions (logf, log2f, powf)?

Can you remove nsz/math2  to avoid confusion?

Yes, please.

Thanks.
