[pacman-dev] [PATCH v2 1/2] Make makepkg compute sizes properly

[Santiago Torres]

Makepkg used to use du --apparent-size to compute the size of the
package. Unfortunately, this would result in different sizes depending
on the filesystem used (e.g., btrfs vs ext4), which would affect
reproducible builds. Use a wc-based approach to compute sizes
