gl_ACL_GET_FILE is a runtime check, it is used internally this way: gl_ACL_GET_FILE([use_acl=1], []) it is written so it would report failure on cross-compile. AC_DEFUN([gl_ACL_GET_FILE], [ AC_CACHE_CHECK([for working acl_get_file], [gl_cv_func_working_acl_get_file], [AC_RUN_IFELSE( [AC_LANG_PROGRAM( [[#include <sys/types.h> #include <sys/acl.h> #include <errno.h> ]], [[return !! (!acl_get_file (".", ACL_TYPE_ACCESS) && errno == ENOENT);]])], [gl_cv_func_working_acl_get_file=yes], [gl_cv_func_working_acl_get_file=no], [gl_cv_func_working_acl_get_file=cross-compiling])]) AS_IF([test $gl_cv_func_working_acl_get_file = yes], [$1], [$2]) ])
you could e-mail bug-gnulib@gnu.org with a suggestion of making the cross-compile code falling back to a link test, but i imagine their answer would be "set gl_cv_func_working_acl_get_file in your environment" which means we can set gl_cv_func_working_acl_get_file in crossdev's config.site files, but i dont think there's any change we'd make to coreutils or any other package that imports the acl module from gnulib.

It's good to know this was previously reported. I spent the last weekend working on this problem (documented at http://forums.gentoo.org/viewtopic-t-971662.html), and independently found this problem in m4/acl.m4 a few days ago and reported it upstream. They quickly pushed a patch to their repository (see message http://lists.gnu.org/archive/html/bug-gnulib/2013-10/msg00062.html). I tested their patch manually (with coreutils and doing a manual autoreconf after updating the m4/acl.m4 copy under coreutils), and it works. Should this be marked as solved upstream, then? In bug 476084 I posted an ebuild with a modification that will let coreutils cross-compile while projects update their copy of the source files from gnulibs. I'll post a patch of it here.
Created attachment 361042 [details, diff] coreutils-8.21.ebuild.patch - generalized check used to override configure variable This patch allows for coreutils to cross-compile while still catching for a bug that is found in Darwin 8.7.0 that is being checked by m4/acl.m4.
