Subject: cross-arm-netbsd linker oddity?

I'm trying to build an a.out NetBSD/arm32 1.5 kernel on a NetBSD/i386 1.5
host using the cross-arm-netbsd package. Everything seems to go smoothly
(using a build script based on the one at
http://www.netbsd.org/Documentation/cross), except that when I examine the
resulting netbsd.gdb file with objdump, the code at the start of the text
segment seems to have been offset by -4064
(-0xfe0) bytes, i.e. linking with "-Ttext F0000000" gives:
$ /usr/local/cross/arm-netbsd/bin/objdump -d netbsd.gdb|head
netbsd.gdb: file format a.out-arm-netbsd
Disassembly of section .text:
00000000effff020 <_kernel_text-0xffffffff00000fe0>:
effff020: e28f1078 add r1, pc, #120
effff024: e8912006 ldmia r1, {r1, r2, sp}
effff028: e0422001 sub r2, r2, r1
effff02c: e3a03000 mov r3, #0
$
Am I missing something, or is the cross-arm-netbsd ld doing something
strange here?
