This fixes the Raspberry Pi optimized memcmp library (with both user-mode and system-mode emulation).
Compared to the previous submission, the main changes are: - I track access endianness by taking into account both SCTLR.B and CPSR.E, to make the code easier to understand (though a little bit more convoluted) - because of this, I prevent execution of BE32 executables with ARMv7 or v8 CPUs. These CPUs do not have SCTLR.B. - because of this, I also included an untested patch to implement BE32 mode in system emulation (BE8 should already work with the previous versions of the series). Note that I also tested the rest only with BE32, since BE8 is not included in linux-user-test-0.3 (it may be possible to convert BE32 to BE8 using ld -r? I haven't tried yet and I'm going to travel for the rest of the weekend). It is a bit late for 2.1, so I wouldn't complain if this is pushed out to the next version.
