rtm-devel4 branch does not compile on zEC12

[Dominik Vogt]

Hi Andi,

we're looking into porting your patches fpr lock elision using Intel's RTM
to the zEC12 processor with IBM's transactional memory stuff.  My first
step
was to clone your rtm-devel4 branch and to compile it on a zEC12, but it
seems some of the code specific to lock elision is not properly hidden from
platforms that do not implement it yet.  In other words:  I get compile
errors.  :-)
