PATCH [google/gcc-4_6-branch]: Include <cstddef> in config/locale/generic/c_locale.h

[H.J. Lu]

Hi,

Revision 172595:

http://gcc.gnu.org/viewcvs?view=revision&revision=172595

added NULL to config/locale/generic/c_locale.h on google/gcc-4_6-branch.
But <cstddef> isn't included, which lead to build failure since NULL isn't
defined.  This patch includes <cstddef>.  OK for google/gcc-4_6-branch?

H.J.
