I use something like this:
old_cflags = env['CFLAGS']
obj = Object(file_path, CFLAGS = old_cflags + flags) # flags is what user
provided in module definition file like below.

The user interface (module definition) looks like this:
flags = ["-DABC", ...]
usw_flags('CFLAGS', flags)
usw_files("elf_obj", ["file1.c", "file2.c", ...])
