[PATCH] Fix a warning in mpx wrappers

[Jakub Jelinek]

Hi!

The following patch fixes a warning in libmpx:
../../../../libmpx/mpxwrap/mpx_wrappers.c:492:8: warning: assignment discards 
'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
     *d = *s;
        ^

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

        * mpxwrap/mpx_wrappers.c (__mpx_wrapper_memmove): Avoid
        -Wdiscarded-qualifiers warning.  Fix up formatting.
