Shortly after the recipe was updated to add ell as a mesh dependency
the way ell was integrated into bluez5 was changed. BlueZ requires
ell only for mesh and for btpclient (external test programs). It will
be ignored unless either mesh or btpclient are selected.
ell can be supplied externally, or it can be copied into the bluez
build directory from an existing sibling source directory. Since
bitbake builds do not provide a sibling source directory tell bluez to
look for it as an external library in the conditions where it's
required.
