            Bug ID: 8861
           Summary: With buildroot 2016.02 trying to build for corei7-avx
                    fails while trying to build host-binutils.
           Product: buildroot
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other

  Target Milestone: ---

Created attachment 6426
  --> https://bugs.busybox.net/attachment.cgi?id=6426&action=edit
Output of the call to make

My environment:
- Fedora release 22 (Twenty Two)
- x86_64
- with a "dnf update" on 10. March 2016

The target is i386, narrowed down to corei7-avx.


Steps to duplicate the problem:
--> wget https://buildroot.org/downloads/buildroot-2016.02.tar.bz2
--> tar xjvf buildroot-2016.02.tar.bz2
--> cd buildroot-2016.02
--> env HOSTCXX=/bin/g++ HOSTCC=/bin/gcc make menuconfig
In Target options select i386, ELF, corei7-avx

--> env HOSTCXX=/bin/g++ HOSTCC=/bin/gcc make
...
>>> host-binutils 2.24 Configuring
... --target=-buildroot-linux-uclibc ...
configure: loading site script /dev/null
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... configure: error: /bin/sh ./config.sub
-buildroot
-linux-uclibc failed
configure: WARNING: cache variable ac_cv_target contains a newline
package/pkg-generic.mk:185: recipe for target
'/home/buschman/wk/buildroot-2016.
02/output/build/host-binutils-2.24/.stamp_configured' failed

--> env HOSTCXX=/bin/g++ HOSTCC=/bin/gcc make savedefconfig
--> cat defconfig 
BR2_x86_corei7_avx=y


The same problem happens when using the up to date version of buildroot
as it was on 09. March 2016 instead.
--> git clone https://git.buildroot.net/buildroot

https://gist.github.com/abuschmann/e2e00e5cb23bb06f94bb

I have send this bug report as a message to the buildroot list on 21. March
2016

Hum, indeed. Thanks for the bug report! Can you try the below patch:

diff --git a/arch/Config.in.x86 b/arch/Config.in.x86

        default "i686"          if BR2_x86_opteron_sse3 && BR2_i386

And then do your configuration from scratch again, and attempt to do the build.
