[patch] compile-fix for targets without LFS

[Bernhard Fischer]

Hi,

For systems that do not have LFS enabled, these two patches are needed.

http://buildroot.uclibc.org/cgi-bin/viewcvs.cgi/*checkout*/trunk/buildroot/package/strace/strace-statfs64-check.patch

	* acinclude.m4: Add check for AC_STATFS64.

The required autoreconf is not part of this patch. Please run autoreconf
before checking this in.

http://buildroot.uclibc.org/cgi-bin/viewcvs.cgi/*checkout*/trunk/buildroot/package/strace/strace-fix-disabled-largefile-syscalls.patch

	* syscall.c: Do not use LFS functions if HAVE_STATFS64
	is not available.

TIA,
