Problem armhf build after huge multilib merge

[thorsten.johannvorderbrueggen@t-online.de]

Hi@all,

i have a problem to build sysroot via buildroot based on a crosstool-ng toolchain ...

Short summary:

I build a crosstoolchain for armhf (https://github.com/tjohann/a20_sdk/blob/master/configs/ct-ng_config) ... to be able to crosscompile i build some libs with buildroot and use them as sysroot ... this was working many times .. but after the multilib merge (https://github.com/crosstool-ng/crosstool-ng/commit/8a4870c2f8788c097d71194cb6d334cef1ae31ab) i will get an error using when i want to build the buildroot parts ... So i think it's a crosstool problem an not a buildroot because it worked bevor the multilib merge ... 

Any suggestions? ...

Pls ignore the 4.9.4 of compiler ... i work on some upgrades but it's the same with "mainline" ... 

Cheers & thx
