Adds a patch for glibc-2.5 so as to no longer reference linux's private

asm/procinfo.h and instead use a glibc internal definition for HWCAP_VFP.

Avoid using asm/procinfo.h
* From: "Joseph S. Myers" <joseph at codesourcery dot com>
* To: libc-ports at sourceware dot org
* Date: Tue, 24 Oct 2006 19:25:12 +0000 (UTC)
* Subject: Avoid using asm/procinfo.h
I previously noted
<http://sourceware.org/ml/libc-ports/2006-08/msg00023.html> that the
use of <asm/procinfo.h>, a Linux-specific kernel header, in
sysdeps/arm/eabi, is an abstraction violation, and that in principle
all the files in sysdeps/arm/eabi should use sysdep.h not
asm/procinfo.h for HWCAP_VFP.
The ARM kernel maintainers have now declared that <asm/procinfo.h>
should not be used outside the kernel at all (and in particular that
headers_install is correct in not exporting it), and that these
definitions will move to a different kernel header. This gives a
concrete reason for making the change to use glibc's internal
definitions, which this patch does, thereby allowing glibc to build
with the exported headers.
2006-10-24 Joseph S. Myers <joseph@codesourcery.com>
* sysdeps/arm/eabi/fclrexcpt.c: Include <sysdep.h> instead of
<asm/procinfo.h>. Use HWCAP_ARM_VFP instead of HWCAP_VFP.
