All of these patches did the same thing, which is already in upstream
config.sub.
With this change, we need only add `use_fresh_config_sub=true` to
the package.sh file.
Note that this is not done automatically in case the port has a modified
config.sub file.
By telling the libtool-related configure checks that the serenity
platform does in fact support shared libs, we can get a VERSYM-free
shared lib out of sqlite. This probably applies to other ports as well.
