When system libraries are removed, ssh.i file links to ssh file:

x86_64-pc-linux-gnu-gcc -o ssh ssh.i -L. -Lopenbsd-compat/ -flto=4
-fuse-linker-plugin -Wl,--as-needed -Wl,-O2 -Wl,-flto -O2 -ggdb -pipe
-march=native -mtune=native -mno-3dnow -mno-sse4.2 -mno-avx -Wl,-z,relro

ls -l ssh

-fpie in LDFLAGS fixed it, thank you!

(Going to open a Gentoo report.)
