[Buildroot] flags to build Qt5 for AMD Geode LX arch ?

[Yann E. MORIN]

David, All,

On 2019-01-29 19:28 +0100, David Picard spake thusly:
> I can build Qt5 successfully. I tested my custom application in QEMU, with

> 
> But on the target, whenever I link one of my programs with Qt5, it

[--SNIP--]

Well, if even a program that is not linked to Qt failes, you won;t solve
that by only "fixing" it in Qt...

In that cas, since your processor is a geode, you have to confiugyure
Buildroot to generate code for that processor, i.e.: BR2_x86_geode=y
