[Qemu-stable] [PATCH] qemu: Fix cross compilation for mipsel |

The configure script was setting HOST_WORDS_BIGENDIAN for all $cpu =
mips|mips64 when cross compiling, since endianness cannot be detected by
running a test program. This includes little endian MIPS though. It
didn't cause any build errors but does prevent QEMU from working
correctly. Instead, detect the endianness similar to how we do for ARM,
by checking for the __MIPSEB__ builtin processor definition.
This is from a hunk in the "[PATCH 8/12] KVM/MIPS: Enable KVM/MIPS for
MIPS targets. Add MIPS GIC code to the build" patch by Sanjay Lal [1].
