[pacman-dev] [PATCH] libmakepkg: when checking for write permissions, handle pre-existing dirs

[Eli Schwartz]

Simplifies the function a bit, but mostly, mkdir -p will never fail if
the directory exists, and therefore makepkg never checks to see if it is
actually writable. On the other hand, it's unnecessary to check if the
directory exists once we know mkdir -p succeeded...
