New comment by Chocimier on void-packages repository https://github.com/void-linux/void-packages/pull/48248#issuecomment-1896142580 Comment: Set `make_use_env=yes` and custom CFLAGS get merged with xbps-src CFLAGS. "tested the changes" means to use this particular build: you coudn't have tested if it doesn't build with xbps-src.
