Fix linking with Python 3.8
The behaviour of python-config --libs has changed in Python 3.8.
For example, compare the output of it with Python 3.7 and 3.8 on an
ArchLinux system:
$ python3.7-config --libs
-lpython3.7m -lcrypt -lpthread -ldl -lutil -lm
$ python3.8-config --libs
-lcrypt -lpthread -ldl -lutil -lm -lm
$
The lack of -lpython in the latter case causes the linker to fail when
attempting to build Yosys against Python 3.8.
Passing the new --embed flag to python-config adds -lpython, just like
earlier versions of Python:
$ python3.8-config --embed --libs
-lpython3.8 -lcrypt -lpthread -ldl -lutil -lm -lm
$
This commit adds code for automatically detecting support for the
--embed flag. If it is supported, it is passed to all python-config
invocations. This fixes building against Python 3.8.
