Restore AC_CHECK_HEADERS in preference to AC_CHECK_HEADER so that the HAVE_*
defines will be generated when needed. This fixes breakage caused by 44703. Only usage where HAVE_* macro is in setup.h.in or was used by configure itself (e.g. HAVE_X11_XLIB_H) is changed. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@47596 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
