This allows to build a complete static LibreOffice on Linux,
except for linked externals. Since LO's static build implies
disabled dynamic loading, one must select one VCL backend to
be compiled in.
See the (large) comment in solenv/gbuild/static.mk trying to
explain, why this implementation was chosen (spoiler: seems
there is no other way) and what is actually implemented.
This will collect all libraries, statics and externals of
executables. If the executable uses components, it will get
linked to all static components. While it works with any
Executable, it just makes sense for soffice.bin, because the
static component map sucks every dependency in, bloating most
other binaries.
In theory on could generate the dependencies based on the list
of used components (see gb_CppunitTest_use_components), then
generate a specific static constructor map, directly include it
in the exe's cxx code and then link the minimal dependencies.
The static LO should build on Linux with:
--enable-customtarget-components
--disable-dynamic-loading
Tested VCL plugin config is:
--disable-gtk3
--disable-gen
--enable-qt5
The partial build support is split into a 2nd patch.
