Switch earmv6{,hf}eb to BE8 in kernel side.
My strategy here is to define _ARM_ARCH_BE8 macro in arm/cdefs.h, if
__ARMEB__ && _ARM_ARCH_6.
Use this macro to determine whether system is compiled for and running on
BE8 mode or not.
Note that, for __ARMEB__, some conditions become compile-time constants
determined by _ARM_ARCH_BE8 macro, e.g., whether BE8 or BE32 are accepted
as a userland binary, or unaligned memory access is possible or not.

If neither COMPAT_NETBSD32 nor MODULAR is defined, there's
no chance for lwp to be running under COMPAT_NETBSD32.

Test (epp->ep_esch->es_emul != &emul_netbsd) instead of

Test (epp->ep_esch->es_emul != &emul_netbsd) instead of
(epp->ep_esch->es_emul == &emul_netbsd32) to determine whether curlwp is
running on COMPAT_NETBSD32 or not.
The former is possible even if COMPAT_NETBSD32 is not built in the main
kernel. Now, compat_netbsd32 module can work on !COMPAT_NETBSD32 kernel.
Discussed with pgoyette.
XXX
Apply similar fixes, i.e., drop ``#ifdef COMPAT_NETBSD32'' conditional
codes from the rest parts of MD codes for aarch64 and mips64.

If we are exec'ing AAPCS and running on armv6+, disable alignment faults
since gcc 4.8 will generate code that uses unaligned accesses.

Support an optional MARCH ELF tag.
Store the MACHINE_ARCH of the executable in mdproc and override sysctl
so that value returned.

COMPAT_NETBSD32 support for ARM. Which is strange since ARM is already
32-bits. But the newer ARM ABI AAPCS changes the alignment of 64-bit
fields so structures need to copied in and out to deal with the alignment
change. This is a kludge but makes debugging of AAPCS support much easier.
