It's not clear what the advantage of such a patch would be. (or generally,
pkg-config for a library like libev).

If "you" are gentoo and you add patches like that, potentially breaking

doing it wrong.

Note that fedora plans to rmeove the pkg-config file because it doesn't
really improve anything (and they have an ethical upstream policy).
