Get rid of some redundant OPSYS checks

Updated based on comments.

Thanks for reviewing comments, will work on new revision.

Actually include new port...

Do not rename, include drm-legacy-kmod, use devel on 12+, as that's recommended and actively developed/fixed.

What GPUs did you test this on? Which architectures? With which DRM? Did you try OpenCL kernels on AMD hardware as this updates lang/clover?

These things keep improving/changing and it would be very helpful for me, as a member of that group of committers trying to keep up with rules and do the right thing, if there were tools assisting me.

Address comments for existing parts of the ports.

Address next rounds of comments.

Unfortunately, portlint didn't complain about this.

Pet portlint.

Version using weak_reference instead of imprecise. Does not build world on power* platforms.

Results for using weak_reference as opposed to imprecise.c

Sorted cpowl into the list and re-instantiated the tgammal comment.

Thanks for the comments!

I've learned a lot already.

universe on riscv reveals that we generally didn't have a powl but instead re-used regular pow. Only gcc on risvc complains about this though. Hence, import powl for ld80 and ld128 from openbsd (and some helper routines) and restrict the workaround to mantissa 53 architectures (power). with this, universe passes on amd64, i386, riscv (except sf but that seems to be expected), arm64, and powerpc.

Add patch to complex.h that was missing.

Correct file locations and alphabetic ordering.

Change to ONLY_FOR_ARCHS_REASON from the amd64 specific one.

Address comments. Unmute INSTALL_DATA, portlint check

Address @mat 's comments and enable i386 compilation.

On a AMD Threadripper 1900X I see "microcode updating..." and output of the CPU information. On a Carrizo APU, I see "microcode updating..." and "done", nothing else. How to check it DTRT?

Thanks for letting me know it was marked broken already! Updated diff accordingly!
