[pacman-dev] [PATCH 5/5] meson-make-symlink.sh: Make compatible with non-GNU ln

[Bjoern Bidar]

> The "-T" flag is something available with GNU ln, but on other
> implementations of ln, "-T" is not an option. So, to make this script
> more portable, a strings check of ln for "GNU coreutils" is done to
> determine if "-T" should be used.

No strings needed just do:
ln --version|grep GNU

Or skip -T even with GNU ln.
