From e21ce89f7ae6964f196086ff325d79e4a3b5acd8 Mon Sep 17 00:00:00 2001 From: Jonathan Liu Date: Tue, 4 Jun 2013 06:04:44 -0700 Subject: [PATCH 1/4] configure: Avoid use of AC_CHECK_FILE for cross compiling The AC_CHECK_FILE macro can't be used for cross compiling as it will result in "error: cannot check for file existence when cross compiling". Replace it with the AS_IF macro.
