On ppc64el, altivec.h redefines bool, pixel and vector which can collide with
c++ types.
This altivec.h inclusion is done by opencl in CL/cl_platform.h .
As altivec.h explains, it's possible to undefine those for C++ compatibility in
libhmsbeagle/GPU/GPUInterface.h where we don't need them and where it fails,
while doing that on the right plateform.
Finally, enable libhmsbeagle1v5 on ppc64el.
