To embed Python into an application, a new --embed option must be passed to "python3-config --libs --embed" to get "-lpython3.8" (link the application to libpython). To support both 3.8 and older, try "python3-config --libs --embed" first and fallback to "python3-config --libs" (without --embed) if the previous command fails. Add a pkg-config "python-3.8-embed" module to embed Python into an application: "pkg-config python-3.8-embed --libs" includes "-lpython3.8". To support both 3.8 and older, try "pkg-config python-X.Y-embed --libs" first and fallback to "pkg-config python-X.Y --libs" (without --embed) if the previous command fails (replace "X.Y" with the Python version). On the other hand, "pkg-config python3.8 --libs" no longer contains "-lpython3.8". C extensions must not be linked to libpython (except on Android, case handled by the script); this change is backward incompatible on purpose. "make install" now also installs "python-3.8-embed.pc".
