llvm10-10.0.0.r2 gets the same.

I was curious what the libarcher* files would be tied to
and found that libarcher is a tool library for an llvm
openmp tool.

But openmp does not seem to be available for armv7 or
aarch64 so the file is not expected to be present for
installation, much like libgomp.so , liniomp5.so ,
libomp.so , and libomptarget.so . Looks like a
%%OPENMP%% prefix is needed in llvm10/pkg-plist for
each of the two libarcher lines.
