pkgrel_bump --auto doesn't work for qt5-qtbase?

Created by: ollieparanoid

As @PureTryOut discovered, our qt5-qtbase binary package was broken in the repository because of a soname bump. However, pmbootstrap pkgrel_bump --auto did not detect this for some reason.

./pmbootstrap.py chroot --add=qt5-qtbase-dev
[00:33:38] (native) install alpine-base
[00:33:48] NOTE: Run 'pmbootstrap pkgrel_bump --auto' to mark packages with outdated dependencies for rebuild. This will most likely fix this issue (soname bump?).
[00:33:48] ERROR: Could not find package 'so:libmysqlclient.so.18' in any aports folder or APKINDEX.
[00:33:48] Run 'pmbootstrap log' for details.
