[oe] Revert Request for linux -> linux-gnu changes

[Graeme Gregory]

Hi, I cannot actually carry out this request as I will be without net
access for the eV meeting.

But it is becoming clear that the linux -> linux-gnu change is throwing
up many issues for arches != linux-gnueabi. Partial fixes have been
implemented but for every fix another issue seems to pop up.

I suggest these changes should be reverted, placed in a branch and
properly merged at a later date after proper review.
