Fix build fauilure on ia64.
Build fails due to bitrot: some definitions
moved off from <sys/pthrace.h> to <asm/ptrace.h>
(similar to other arches).
fetch.c:39:26: error: field 'regs' has incomplete type
struct pt_all_user_regs regs;
^~~~
fetch.c:209:25: warning: 'struct ia64_fpreg' declared inside parameter list will not be visible outside of this definition or declaration
fpreg_to_double (struct ia64_fpreg *fp) {

fetch.c: In function 'fpreg_to_double':
fetch.c:211:45: error: dereferencing pointer to incomplete type 'struct ia64_fpreg'
