OpenBSD: v0.22 (without vulkan feature) works, but not v0.23

[rennis250]

Hello,

I've been happily using the glfw crate on OpenBSD, so many thanks! :-)

However, I found out today that v0.23 does not work on OpenBSD. To get v0.22 to work, one needs to disable the vulkan feature, but even doing that doesn't work with v0.23. I get the following errors:

(note that all of the "aaaa"'s after filenames below was changed by me on purpose).

error: linking with `cc` failed: exit code: 1
