Currently, when running the packaging/android/build.sh from a source
tree that has been used for desktop builds, libdivecomputer wants a
make distclean. This is inconvinient, and is caused by building
libdivecomputer in source. Now, configure and build libdivecomputer
in a new subdirectory, allowing to run the android build script
from the same source tree as the desktop (both desktop and mobile)
builds.
