Manually updating the LINGUAS file is error prone because new
translations can be added at any time via translate.moblin.org.
Better create the file automatically on each build/release.
Removed a spurious package check for synthesis which was reintroduced
during the recent code cleanup and merging.
Fixed compilation with --enable-unit-tests and/or --enable-integration-tests.
CPPUnit header files were not included properly.
When at least one of these enable options is used, client-test is built
as part of the normal "make all" and installed in bindir as part of
"make install". The test files go into the docdir.
