[pacman-dev] [PATCH] makepkg: deterministic PKGINFO libprovides for multiple library versions

[anthraxx at archlinux.org]

From: Levente Polyak <anthraxx at archlinux.org>

While iterating over the provides array, the find call for locating a
shared library may result in listing multiple entries which by itself
does not produce a stable deterministic order and may vary depending on
the underlying filesystem.
To provide a stable listing and a reproducible .PKGINFO file the result
of find is piped to sort with a static LC_ALL=C localisation.
