getpagesize: Fix compilation error on Android.
* m4/getpagesize.m4 (gl_CHECK_FUNC_GETPAGESIZE): New macro.
(gl_FUNC_GETPAGESIZE): Invoke it instead of AC_CHECK_FUNC.
* m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): Don't invoke
AC_CHECK_FUNC. Instead, invoke gl_CHECK_FUNC_GETPAGESIZE and define
HAVE_GETPAGESIZE accordingly.
* modules/getcwd (Files): Add m4/getpagesize.m4.
