I couldn't reproduce this locally, perhaps because I have the wrong number
of cores. However, exploring the build graph with:

    ninja -t browse plugins/filebrowser/5f8d977@@filebrowser@sha/libfilebrowser.so.symbols

showed that there was no dependency between
gedit-file-browser-plugin.c.o and gedit-file-browser-enum-types.h.
Adding the generated gedit-file-browser-enum-types.h to the sources for
this shared_library() causes an (order-only) dependency to be added,
ensuring that gedit-file-browser-enum-types.h is generated before
gedit-file-browser-plugin.c is compiled.
