        src/sys/compat/linux/common: linux_exec_elf32.c
        src/sys/compat/linux32/common: linux32_exec_elf32.c
        src/sys/compat/netbsd32: netbsd32_exec_elf32.c
        src/sys/compat/svr4_32: svr4_32_exec_elf32.c
        src/sys/kern: exec_elf.c

Log Message:
Zero-fill the ELF auxiliary vectors. Otherwise, on 64bit systems, the
padding between a_v and a_type contains kernel garbage, therefore
exposed to userland.
