libxc: fix link error on ia64

On ia64, xen-unstable 19698:f72d26c00002 cannot be built:
../../tools/libxc/libxenguest.so: undefined reference to
`xc_core_arch_map_p2m_writable'
../../tools/libxc/libxenguest.so: undefined reference to `xc_map_m2p'

Because xc_offline_page.c requires xc_map_m2p() in xc_domain_save.c,
xc_offline_page.c must be compiled only if CONFIG_MIGRATE=3Dy.
