package/libiberty: remove package

host-libiberty was only used by host-prelink-cross, which has now been
removed.

The dependency of host-gdb on host-libiberty was not because it was
needed, but because if both host-libiberty and host-gdb were built,
host-gdb should be built after host-liberty. See commit
f0a583ddc4c2cab121330284e316f54229dee492 ("package/gdb: depend on
libiberty")

Fixes:
