bpo-36465 modified the ABI of debug build so release and debug build now have the same ABI.

bpo-21536 modified how C extensions are built: they are no longer linked to libpython.

In a debug build, it becomes possible to load a C extension built in release mode:
https://bugs.python.org/issue21536#msg340821

But I had to modify SOABI for that.

I propose to modify how Python looks for C extensions: look also for dynamic libraries without the "d" SOABI flag and for C extensions built using the stable ABI.

Release build:

$ ./python -c 'import _imp; print(_imp.extension_suffixes())'
['.cpython-38-x86_64-linux-gnu.so', '.abi3.so', '.so']

Debug build, *WITHOUT* my change:

$ ./python -c 'import _imp; print(_imp.extension_suffixes())'
['.cpython-38d-x86_64-linux-gnu.so', '.so']

Debug build, *WITH* my change:

$ ./python -c 'import _imp; print(_imp.extension_suffixes())'
['.cpython-38d-x86_64-linux-gnu.so', '.cpython-38-x86_64-linux-gnu.so', '.abi3.so', '.so']
