So this looks like a custom or at least unusual Linux distro (or at
least build of gcc), and you use custom build options.

It is rather unusual to have a CPU supporting SSE2 yet not SSSE3 these
days.  I'd guess this non-detection of SSSE3 is a side-effect of the
overridden CFLAGS, but I can't reproduce it.  So are you actually on a
currently rare early x86-64 CPU from prior to 2006 or so?  What is it?

So you'd have a highly unoptimal build, even if the build worked,
because of you having overridden the CFLAGS.

None of this is directly related to the build failure, but it indicates
that your build is highly unusual in general.

As to the build failure, what's your version of "make" - e.g., what does
"make -v" say?

magnum, when we build without OpenCL support, can we possibly have it
skip copying of the OpenCL kernels?  (The copying should have succeeded
anyway, but let's use this as a reminder of this possible improvement.)
