The hide pattern .xen-syms.[013] leaves pass 2 visible. On x86
LAST_LINKING_PASS is 2, so that is the final link. On Arm
LAST_LINKING_PASS is 3 and the final image is .xen-syms.3. Pass 2 is
usually only a symlink, so Eclair saw no program link and reported every
translation unit as unreachable.
During analysis preparation, read LAST_LINKING_PASS from the architecture
makefile and the pass numbers from the foreach list in
xen/scripts/Makefile.link. Hide every pass except that one. An earlier
pass that is a real link stays hidden. The generator runs from
generate_ecl.sh, together with the other ECLAIR configuration scripts.
Fixes: a401b5c9dc ("Eclair: re-enable scanning of the (almost) final linking step")
