Actually this occurred to me before libress was adopted. After libressl
was introduced, I also changed Bootstrap script, libressl APKBUILD,
kernel config to adop libressl too, but still the bug. So I guess it's
more likely coming from abuild. Here are some of my patches, in case
you might want to have a look.
