[oe] gcc-cross build fail

[Otavio Salvador]

[ Added Khem in CC since he is the patch author ]

Hello,

Commit 051c2ca2a9b0dd30556a188e1d3c941b84fa5a80 breaks the build of
gcc-cross for i586-generic (I am using an amd64 host system) and
reverting it fixes the problem.

As follows:

...

It looks like a linaro related regression and it looks like linaro
people are aware of this:

Any idea which change of the patch might be responsable for it?
