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.

[Buildroot] [Bug 10156] glibc compilation fails for X86 32bits (i386)

[bugzilla at busybox.net]

https://bugs.busybox.net/show_bug.cgi?id=10156

--- Comment #1 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com> ---
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 ?
