That just raises the same question though. Why are we having to
explicitly list the dependencies on an ELF platform? Why are your
libraries missing the "NEEDED" entries that should make this just work
automatically?
And incidentally this explanation implies that the patch doesn't need
-lssl since there's no -lssl in the gss configure line either. It
looks like -lcrypto was all that was needed here. Which makes sense
since otherwise the krb5 test would also be broken.
Finally do you happen to know which other BSD flavours use the same
linker option to strip unused symbols? I assume OpenBSD didn't write
their own linker and suspect you're using the same one as any other
variant that hasn't switched to GNU ld or some other toolchain.
