I actually don't expect to have many conditionals for Flatpak support
in the spec file. There may need to be fixes - for example, if %files
references /usr/share rather than %{_datadir} - but those fixes should
just work for the main build as well. If Fedora packages just hardcoded
FHS paths, then all the path macros wouldn't be necessary to start
with!
An example of where conditionals may be useful is when a library is
bundled into a Flatpak - the rebuild for the flatpak could skip
building the developer docs because they have complicated build
dependencies (graphviz or whatever.) We'll have to see how frequent
that is as we work through real examples.
