* target.h: (HAVE_CONTINUABLE_WATCHPOINT): Define.
(target_ops): Add to_have_continuable_watchpoint.
* target.c (update_current_target): Add INHERIT line for
to_have_continuable_watchpoint.
* infrun.c: Remove HAVE_CONTINUABLE_WATCHPOINT defines.
* config/i386/nm-i386.h, config/i386/nm-i386sco5.h,
config/i386/nm-i386sol2.h, config/s390/nm-linux.h,
config/sparc/nm-sun4sol2.h: HAVE_CONTINUABLE_WATCHPOINT defined as 1.
