-Subject: [PATCH] Enable cross compiling
-
-During the audit build, several lookup tables are generated as header
-files that are then linked in with the executables. This process is done
-by a C application that needs to be able to be run on the host. The
-current Makfile structure tries to build these executables for the
-target instead of the host where they cannot be executed. This patch
-reworks the Makefile structure to build for the correct platform.
-
-This is revision 2 of this patch and is a complete rework of the
-original patch. I have tested that it builds on an x86_64 ubuntu
-platform and tested it running on an ARM cross compile platform.
-
-The ax_prog_cc_for_build.m4 file was obtained from GNU at the link
-below.
-http://www.gnu.org/software/autoconf-archive/ax_prog_cc_for_build.html

-+# SYNOPSIS
-+#
-+# AX_PROG_CC_FOR_BUILD
-+#
-+# DESCRIPTION
-+#
-+# This macro searches for a C compiler that generates native executables,
-+# that is a C compiler that surely is not a cross-compiler. This can be
-+# useful if you have to generate source code at compile-time like for
-+# example GCC does.
-+#
-+# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
-+# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
-+# The value of these variables can be overridden by the user by specifying
-+# a compiler with an environment variable (like you do for standard CC).
-+#
-+# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
-+# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
-+# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
-+# substituted in the Makefile.
