Hi,

I'm seeing some test failures on the trippels-powerpc64le-gcc-6.0 tester 
that amount to Boost.Math failing to build because the quadmath.h header 
is missing.

I understand that gcc 6.0 is an unreleased compiler, but the error is 
probably not a consequence of a compiler bug. Besides, another tester, 
Flast-FreeBSD10-gcc-6.0.0~gnu++11, passes. Is it possible that the 
header is not provided for powerpc64le? Or is an optional dependency 
whose presence is misdetected? Is this a known problem?
