+From e60cc1b011bf0f1acdb7e5168b7bed4ebb78c91f Mon Sep 17 00:00:00 2001
+From: Bruce Ashfield <bruce.ashfield@windriver.com>
+Date: Wed, 9 Jan 2013 16:24:39 -0500
+Subject: [PATCH] scripts/Makefile.headersinst: install headers from scratch file
+
+If headers_install is executed from a deep/long directory structure, the
+shell's maximum argument length can be execeeded, which breaks the operation
+with:
+
+| make[2]: execvp: /bin/sh: Argument list too long
+| make[2]: ***
+
+By dumping the input files to a scratch file and using xargs to read the
+input list from the scratch file, we can avoid blowing out the maximum
+argument size and install headers in a long path name environment.
+
