install_name_tool problem with symlinks on Xcode 12.2

Heads up! install_name_tool in Xcode 12.2 -- the version we are using for Big Sur -- has a bug that could affect ports. If you give install_name_tool a path to a symlink to a library, you might expect it to modify the library, and that's what it did in previous versions of Xcode. But in Xcode 12

llvm/clang/lldb -devel on Apple Silicon

So the latest build of llvm etc did build through and install on Apple Silicon That is a milestone of sorts I think. This allows openmp, and the first alternative compiler to try for failed builds. I’ll move this into llvm/clang 11 soon, once I finish wrestling with the github PG. Best, Ken

Re: llvm/clang/lldb -devel on Apple Silicon

sadly, today, flang is pretty much useless for us. It can only process source and send it off to another fortran compiler ( a commercial one from the company that donated flang to the community) to be compiled. But obviously that will disappear in due course, and flang will work independently

port maintainers: please test check for implicit decls

Hello port maintainers, I just merged https://github.com/macports/macports-base/pull/217, a sanity check that runs after the configure phase to detect implicitly declared functions in autotools configure scripts. This will become a significant problem with the release of Big Sur, since Apple has
