    i64: fix missing exp2f, log2f and powf symbols in libm.a [BZ #23822]
    
    When new symbol versions were introduced without SVID compatible
    error handling the exp2f, log2f and powf symbols were accidentally
    removed from the ia64 lim.a.  The regression was introduced by
    the commits
    
    f5f0f5265162fe6f4f238abcd3086985f7c38d6d
    New expf and exp2f version without SVID compat wrapper
    
    72d3d281080be9f674982067d72874fd6cdb4b64
    New symbol version for logf, log2f and powf without SVID compat
    
    With WEAK_LIBM_ENTRY(foo), there is a hidden __foo and weak foo
    symbol definition in both SHARED and !SHARED build.
    
    	[BZ #23822]
    	* sysdeps/ia64/fpu/e_exp2f.S (exp2f): Use WEAK_LIBM_ENTRY.
    	* sysdeps/ia64/fpu/e_log2f.S (log2f): Likewise.
    	* sysdeps/ia64/fpu/e_exp2f.S (powf): Likewise.
    
    (cherry picked from commit ba5b14c7613980dfefcad6b6e88f913e5f596c59)
