In general a mature (i.e. optimized) C program is going to be faster
than a Python program to do the same task.

os.path.walk() is more-or-less obsolete, os.walk() does the same job
and is much easier to use. I don't know if it is any faster though.
If I understand your code, you want to find every file named src.mk
that is in a directory named src. With os.walk() it would look like
this:
for dirpath, dirnames, filenames in os.walk(component_dir):
if dirpath.endswith('/src'):
if 'src.mk' in filenames:
walk_lst_result.append(os.path.join(dirpath, 'src.mk')
# or just handle the file here, no need to make the list
