+Subject: [PATCH] Remove --no-undefined linker flag for python 3.8
+
+The -Wl,--no-undefined linker flag cannot be consistently applied for
+all projects linked against SoapySDR because starting in python3.8 the
+--ldflags no longer include the python library, and there are supposed
+to be missing symbols which will be provided at runtime by the
+interpreter.
