[strongSwan] strongswan 5.0.1 ipsec configuration load issue

[Martin Willi]

Hi Jordan,

I think this is problematic. The build options have changed with the use
of config.h, and I don't know how this behaves when not using it.

If you want to use the same configuration, I recommend to pass just the
same options to ./configure. We try hard to introduce new options
disabled by default, and keep enabled options enabled.

I have really no idea what's wrong. But I'd try to start from a
clean, ./configure'd build before tracking this down further.
