Symphorien Gibol a6a29e07bc nixos/fontconfig/make-fonts-cache: don't fail to clean the cache
Today I couldn't rebuild because of:
[...]
/nix/store/lxkrsrlqplz2n75hvpq6vr0gam0gfgrl-font-cursor-misc-1.0.3/lib/X11/fonts/misc: skipping, existing cache is valid: 1 fonts, 0 dirs
/var/cache/fontconfig: cleaning cache directory
/nix/store/xq3c44ha15pfa5a9mv1z9mni3cfghsna-fc-cache: cleaning cache directory
