 To be entirely complete: in Python 2.7, it's called _sysconfigdata.py (without
arch specification). However, since the thing is in a $(wildcard), nothing
matches (even if we would use PYTHON_VERSION_MAJOR), so
_PYTHON_SYSCONFIGDATA_NAME is set to empty.

 In [1] I set _PYTHON_SYSCONFIGDATA_NAME to _sysconfigdata.py for Python2.7 (but
only in meson-package, I'm not sure why...), but Adam says that this breaks
libglib2...

 Anyway, this patch is definitely correct.

 Arnout
