buildroot .config

With arch i386 (see config file), The latest buildroot versions fails to compile glibc (2.24 or 2.25).
tested with : 2017.05.2 and 2017.02.5

The same config works fine with buildroot version 2017.02.3.

Comment 1 Thomas Petazzoni 2017-08-03 11:26:01 UTC 
Thanks for the bug report. Since the regression was introduced between 2017.02.3 and 2017.02.5, could you do a "git bisect" to find where the problem is ?
Comment 2 Thomas Petazzoni 2017-08-05 13:47:22 UTC 
I've submitted a patch that fixes this issue, see https://patchwork.ozlabs.org/patch/798221/.
