  I noticed a few uses of copysign in generic GLIBC sources - these should be __copysign
to avoid namespace issues and enable inlining.

Directly checked in as trivial change.

2015-04-22  Wilco Dijkstra  <wdijkstr@arm.com>

        * math/k_casinh.c (__kernel_casinh): Use __copysign.
        * sysdeps/ieee754/dbl-64/wordsize-64/s_nearbyint.c
        (__nearbyint): Likewise.
        * sysdeps/ieee754/ldbl-opt/nldbl-copysign.c
        (copysignl): Likewise.
