I'm not an expert about this macro. but I'd do something like this:
m4_define([MY_PROLOGUE], [whatever])
m4_define([MY_BODY], [whatever2])
m4_define([MY_PROGRAM], [AC_LANG_PROGRAM([MY_PROLOGUE], [MY_BODY])])
...
AC_LINK_IFELSE([MY_PROGRAM], [action-if-true], [action-if-false])
if <not cross compiling>; then
AC_RUN_IFELSE([MY_PROGRAM], [action-if-true], [action-if-false])
fi
HTH,
