perf: build: Set Python configuration for cross compilation

Browse Source 
Python configuration has dedicated folders for different architectures.
For example, Python 3.11 has two folders as shown below, one for Arm64
and another for x86_64:

  /usr/lib/python3.11/config-3.11-aarch64-linux-gnu/
  /usr/lib/python3.11/config-3.11-x86_64-linux-gnu/

This commit updates the Python configuration path based on the
compiler's machine type, guiding the compiler to find the correct path
for Python libraries. It also renames the generated .so file name to
match the machine name.
