docs/llvmpipe: document ppc64le as alternative architecture to x86.
Power8, Power8NV, and Power9 are supported on an equal footing with X86.

The Gallium llvmpipe driver is a software rasterizer that uses LLVM to
do runtime code generation.
Shaders, point/line/triangle rasterization and vertex processing are
-implemented with LLVM IR which is translated to x86 or x86-64 machine
+implemented with LLVM IR which is translated to x86, x86-64, or ppc64le machine
code.
Also, the driver is multithreaded to take advantage of multiple CPU cores
(up to 8 at this time).

yield the most efficient code. The fewer features the CPU has the more
