Anyway, this indeed has helped a lot. But not enough. I am not sure if
the number of libraries merged this way can be easily increased much
at this stage of gbuildification.

I don't know what is much but it can be easily increased I think.
At least conditionally for Android.

Originally I understood we want to merge libraries which are "always used".
I have a year old list of libraries (attached) where I also mark the
status of modules.
It was created by starting ./soffice --calc ./soffice --writer ... 5
different runs.
'5    ucpgvfs1.uno.so             ->    ucb              <- GNU      <- TAIL'
says that the library was loaded 5 times (always) and is from
tail_build's module ucb.

But currently we are merging also fwl and fwm which are not used at
the start of Libreoffice.
I think we can merge these only for Android and also add more small
component libs like fileacc.
Attached patch.

The simple rules for adding:
- library needs to be from tail_build
- It must not create circular dependencies because of linking chains

All these modules are candidates for adding into tail_build (adding of
connectivity immediately allows adding of other modules: svl, sot,
unixODBC). And I think there will be a couple of other candidates after
these three branches are all merged into master.

shell/, unotools/. (Well, we need to move crashrep/ behind tail_build)
Next blocker would be pyuno, blocking sax.

Actually I have created patch based on feature/gbuild_conversions which
adds fsstorage, svl, sot and vcl to libmerged. I am waiting for the merge.
But vcl is big, if there are problems with linking..

Best,
Matus
