Improve portability to Alpine linux

This PR takes two steps to improve portability to Alpine Linux:

• Brings in the changes from
  Add missing include #include <sys/types.h> to support ssize by janciesko · Pull Request #105 · Qthreads/qthreads · GitHub into the bundled
  qthreads
• Adjusts chplenv scripts to, as a backup strategy, look for clang
  dependencies in /usr/include, /usr/lib, and /usr/bin since that is
  where Alpine installs them. This code includes a check that the
  version number matches the llvm-config version.

Resolves #19404.

Reviewed by @ronawho - thanks!

• default configuration on Alpine Linux builds and make check
  succeeds

• make and make check succeed in default configuration on Mac OS
  X + Homebrew

• full local testing
