Conflicting header files in /usr/include installed by libc6-dev and linux-libc

[Johnson Steward <i@jsteward.moe>]

Hi all,

I'm currently working with gccgo on a sparc64 machine (namely a Sun
Enterprise T5120) in a debian sid chroot. Seems like the packages
linux-libc-dev:sparc64 and libc6-dev:sparc64  are installing
conflicting header files:

linux-libc-dev:sparc64: /usr/include/sparc64-linux-gnu/asm/termbits.h
libc6-dev:sparc64: /usr/include/sparc64-linux-gnu/bits/ioctl-types.h

They define the same struct twice (though with exactly the same
contents, this causes gcc to complain):

root@sparc:~/go/src/github.com/ncw/rclone/vendor/golang.org/x/sys/unix#
./mkall.sh

The details of the two packages installed are as follows.
