Bug Description

I've found a disagreement between:

$ python-config --libs
-lpthread -ldl -lutil -lm -lpython2.7

and

$ pkg-config python --static --libs
-lpthread -ldl -lutil -lpython2.7

It seems to me that pkg-config is missing is missing -lm. The full list of packages is also larger than specified here. An attempt to embed python interpreter in a hello-world library will fail with multiple linkage issues due to missing openssl, libz and a few other things.

see the upstream issue.

For now to build an embedded interpreter, use SYSLIBS and MODLIBS directly (sysconfig.get_config_var)
