I check /tmp/portage/dev-lang/rust-9999/temp/cargo-install.FLHiZdEvovMj/debug/build/libgit2-sys-294bff880f16dcf0/out/lib directory but it doesn't exists. The parent folder contains only build directory which contains required file:

Can also reproduce on Arch PKGBUILD too. The reason remains unknown.

Can also confirm on Funtoo

It seems like the issue is fixed by adding emake dist after first emake in src_install()
