Build break on amd64

[Paul Goyette <paul%whooppee.com@localhost>]

With sources updated just a few minutes ago, I get

In file included from /build/netbsd-local/src/sys/kern/exec_elf32.c:39:0:
/build/netbsd-local/src/sys/kern/exec_elf.c: In function 'exec_elf32_makecmds':
/build/netbsd-local/src/sys/kern/exec_elf.c:739:2: error: 'p' undeclared 
(firstuse in this function)
/build/netbsd-local/src/sys/kern/exec_elf.c:739:2: note: each undeclared 
identifier is reported only once for each function it appears in

This references the following code:

#if defined(PAX_MPROTECT) || defined(PAX_SEGVGUARD) || defined(PAX_ASLR)
        p->p_pax = epp->ep_pax_flags;
#endif /* PAX_MPROTECT || PAX_SEGVGUARD || PAX_ASLR */


I suspect the following commit:
