create --enable-mergelibs=more

The existing --enable-mergelibs is in use by Linux distro people,
who do not want any further mergeing because they want to be
able to split libreoffice up into things like nogui, calc, writer,
dbaccess, etc.

So this work is to enable combining even more into libmerged
for platforms like Windows and macOS and COOL, where we really
want everything in one big lump of code.
