Bug 274108: devel/libnotify: fix build with lld 17
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274108



--- Description ---
Building devel/libnotify with lld 17 results in the following link error:

This is because lld 17 defaults to errors when undefined symbols are referenced
in linker version scripts.

Apparently the __progname and environ symbols (which usually come from libc,
not libnotify.so) were explicitly added in:

    Fix build with old binutils.

    Somehow linker scripts should not hide __progname and environ from symbols.

    Reported by:    kib

but it is unclear what the original error was, or how old "old" is, and there
is no reference to a PR.

In any case, I think the devel/libnotify/files/patch-libnotify_libnotify.map
file can simply be deleted now.
