This is a known issue and it only affects Loongson buildds.
Interestingly mipsel-manda-01 is Loongson and didn't fail there so there
may be a random element involved here. I don't think anyone's tracked
down the underlying issue though.

For the moment, I'll rebuild libreswan again and hope a good buildd is
picked.
