- Issue #8032: For gdb7, a python-gdb.py file is added to the build,
allowing to use advanced gdb features when debugging Python.
- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment
variable anymore. It also forwards the LDFLAGS settings to the linker
when building a shared library.
