[tz] [PROPOSED PATCH] port 'environ' decl to Solaris 10

[Paul Eggert]

POSIX says apps must declare 'environ' themselves.  Although this
is not necessary on GNU/Linux with _GNU_SOURCE defined, it is
needed with stricter environments like Solaris 10.
* date.c, zdump.c (environ): Declare even if HAVE_POSIX_DECLS.
