[Buildroot] [PATCH] ncftp: fix host/target confusion

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2017-02-28 23:54 +0100, Thomas Petazzoni spake thusly:
> The ncftp build process tries to build and run a small program called
> ccdv to beautify the build process output. If it manages to build and
> run it, then it uses it.
> 
> Unfortunately, this doesn't work well when the target architecture is
> close to the host architecture, but not exactly the same. Because both
> architectures are close to each other, the test run of ccdv succeeds,
> but real use of ccdv during ncftp build process causes an Illegal
> instruction issue.
> 
> This for example happens with the CodeSourcery AMD64 toolchain, on a
> build machine running an i7-4600U, and has been detected in the
> autobuilders since the CodeSourcery AMD64 toolchain was upgraded at
> the end of January:
> 
>   http://autobuild.buildroot.net/?reason=ncftp-3.2.6
> 
> The issue was also reported by Christopher Arguin back in July 2016:
> 
>   http://lists.busybox.net/pipermail/buildroot/2016-July/168026.html
> 
> and at the time, we identified that simply disabling the ccdv tool, by
> passing --disable-ccdv, was enough to solve the issue. But Christopher
> never submitted the patch, so the problem remained unfixed.
> 
> Therefore, we pass --disable-ccdv to the configure script, which
> fixes:
