I replaced the second patch with this one and did a build test.
Till v16, I had tested the whole series (build + run) on both a POWER8
system (with 4K and 64K page sizes) and a Skylake SP system but for
x86_64 only. Following that, I could only do a build test locally on
my laptop for i386 and x86_64 on my laptop as I did not have access to
the Skylake system anymore.

This is how I tested the build process:
