Summary:                    Compliation failure for arm due to
sendfile/sendfile64 conflict
Description: 
When using daily snapshot with buildroot, building for StrongARM (SA1100),
the file toolchain_build_arm/uClibc/libc/sysdeps/linux/common/sendfile.c
fails to compile with the following errors:
  CC libc/sysdeps/linux/common/sendfile.os
libc/sysdeps/linux/common/sendfile.c:19: error: conflicting types for
'sendfile64'
./include/sys/sendfile.h:47: error: previous declaration of 'sendfile64'

forgot to mention: using gcc-4.0.2

Looks like mips and i386 kernel headers define sendfile64, while arm
headers do not (in an '#if 0' block).

Problem was that I was using 2.4.31 kernel headers. Moved to 2.6.12 headers
and __NR_sendfile64 is defined, so the problematic block at the bottom of
sendfile.c is avoided.
