Python 3.8 linking error

This error was reported by an OS-X user when compiling hamlib.https://github.com/Hamlib/Hamlib/issues/350

the problem is with the python m4 macros -- they are trying to get the ldflags from distutils.sysconfig, instead of calling python3_config. the returned ldflags are not prefixed with /Library/Frameworks ... python3_config --ldflags gives different ldflags. I am not sure if those are correct.


os x issue.
I built hamlib for python 2.7. Trying to do the configure for 3.8, I got an error, because the extra linking flag is broken:

Could not link test program to Python. Maybe the main Python library has been
installed in some non-standard library path. If so, pass it to configure,
via the LIBS environment variable.

ERROR!
You probably have to install the development version of the Python package
for your distribution. The exact name of this package varies among them.

See `config.log' for more details
