>Description:
x68k-current (20140227) build fails at sys/arch/x68k/stand/boot
with a strange error message on FreeBSD-8.2/amd64 host.
This failure continues from at least 20140101.
(I have no build log during from 201308 to 201312 :(
Last successful build is 20130801 on this host.

Of course, I tried a clean build, but got the same result.

On the other hand, the build on NetBSD-6.1/i386 succeeded
with the same source tree (20140227) shared by NFS.

Therefore, I think that some problem happened in a crossbuild
tool during from 201308 to 201312.

The uname which build fails is "FreeBSD 8.2-RELEASE-p9 amd64".

build log is
